assignment operator in php

Language Reference

Assignment Operators

The basic assignment operator is "=". Your first inclination might be to think of this as "equal to". Don't. It really means that the left operand gets set to the value of the expression on the right (that is, "gets set to").

The value of an assignment expression is the value assigned. That is, the value of " $a = 3 " is 3. This allows you to do some tricky things: <?php $a = ( $b = 4 ) + 5 ; // $a is equal to 9 now, and $b has been set to 4. ?>

In addition to the basic assignment operator, there are "combined operators" for all of the binary arithmetic , array union and string operators that allow you to use a value in an expression and then set its value to the result of that expression. For example: <?php $a = 3 ; $a += 5 ; // sets $a to 8, as if we had said: $a = $a + 5; $b = "Hello " ; $b .= "There!" ; // sets $b to "Hello There!", just like $b = $b . "There!"; ?>

Note that the assignment copies the original variable to the new one (assignment by value), so changes to one will not affect the other. This may also have relevance if you need to copy something like a large array inside a tight loop.

An exception to the usual assignment by value behaviour within PHP occurs with object s, which are assigned by reference. Objects may be explicitly copied via the clone keyword.

Assignment by Reference

Assignment by reference is also supported, using the " $var = &$othervar; " syntax. Assignment by reference means that both variables end up pointing at the same data, and nothing is copied anywhere.

Example #1 Assigning by reference

The new operator returns a reference automatically, as such assigning the result of new by reference is an error.

The above example will output:

More information on references and their potential uses can be found in the References Explained section of the manual.

PHP - Assignment Operators Examples

You can use assignment operators in PHP to assign values to variables. Assignment operators are shorthand notations to perform arithmetic or other operations while assigning a value to a variable. For instance, the "=" operator assigns the value on the right-hand side to the variable on the left-hand side.

Additionally, there are compound assignment operators like +=, -= , *=, /=, and %= which combine arithmetic operations with assignment. For example, "$x += 5" is a shorthand for "$x = $x + 5", incrementing the value of $x by 5. Assignment operators offer a concise way to update variables based on their current values.

The following table highligts the assignment operators that are supported by PHP −

In this article, we will see how to use the operators in PHP, & various available operators along with understanding their implementation through the examples.

Operators are used to performing operations on some values. In other words, we can describe operators as something that takes some values, performs some operation on them, and gives a result. From example, “1 + 2 = 3” in this expression ‘+’ is an operator. It takes two values 1 and 2, performs an addition operation on them to give 3.

Just like any other programming language, PHP also supports various types of operations like arithmetic operations(addition, subtraction, etc), logical operations(AND, OR etc), Increment/Decrement Operations, etc. Thus, PHP provides us with many operators to perform such operations on various operands or variables, or values. These operators are nothing but symbols needed to perform operations of various types. Given below are the various groups of operators:

Arithmetic Operators
Logical or Relational Operators
Comparison Operators
Conditional or Ternary Operators
Assignment Operators
Spaceship Operators (Introduced in PHP 7)
Array Operators
Increment/Decrement Operators
String Operators

Let us now learn about each of these operators in detail.

Arithmetic Operators:

The arithmetic operators are used to perform simple mathematical operations like addition, subtraction, multiplication, etc. Below is the list of arithmetic operators along with their syntax and operations in PHP.

Note : The exponentiation has been introduced in PHP 5.6.

Example : This example explains the arithmetic operator in PHP.

Logical or Relational Operators:

These are basically used to operate with conditional statements and expressions. Conditional statements are based on conditions. Also, a condition can either be met or cannot be met so the result of a conditional statement can either be true or false. Here are the logical operators along with their syntax and operations in PHP.

Example : This example describes the logical & relational operator in PHP.

Comparison Operators: These operators are used to compare two elements and outputs the result in boolean form. Here are the comparison operators along with their syntax and operations in PHP.

Example : This example describes the comparison operator in PHP.

Conditional or Ternary Operators :

These operators are used to compare two values and take either of the results simultaneously, depending on whether the outcome is TRUE or FALSE. These are also used as a shorthand notation for if…else statement that we will read in the article on decision making.

Here, the condition will either evaluate as true or false. If the condition evaluates to True, then value1 will be assigned to the variable $var otherwise value2 will be assigned to it.

Example : This example describes the Conditional or Ternary operators in PHP.

Assignment Operators: These operators are used to assign values to different variables, with or without mid-operations. Here are the assignment operators along with their syntax and operations, that PHP provides for the operations.

Example : This example describes the assignment operator in PHP.

Array Operators: These operators are used in the case of arrays. Here are the array operators along with their syntax and operations, that PHP provides for the array operation.

Example : This example describes the array operation in PHP.

Increment/Decrement Operators: These are called the unary operators as they work on single operands. These are used to increment or decrement values.

Example : This example describes the Increment/Decrement operators in PHP.

String Operators: This operator is used for the concatenation of 2 or more strings using the concatenation operator (‘.’). We can also use the concatenating assignment operator (‘.=’) to append the argument on the right side to the argument on the left side.

Example : This example describes the string operator in PHP.

Spaceship Operators :

PHP 7 has introduced a new kind of operator called spaceship operator. The spaceship operator or combined comparison operator is denoted by “<=>“. These operators are used to compare values but instead of returning the boolean results, it returns integer values. If both the operands are equal, it returns 0. If the right operand is greater, it returns -1. If the left operand is greater, it returns 1. The following table shows how it works in detail:

Example : This example illustrates the use of the spaceship operator in PHP.

PHP Operators

Summary : in this tutorial, you will learn about PHP operators and how to use them effectively in your script.

An operator takes one or more values, known as operands, and performs a specific operation on them.

For example, the + operator adds two numbers and returns the sum of them.

PHP supports many kinds of operators:

Arithmetic Operators

Assignment operators, bitwise operators, comparison operators.

Increment/Decrement Operators

Logical Operators

Concatenating Operators

The arithmetic operators require numeric values. If you apply them to non-numeric values, they’ll convert them to numeric values before carrying the arithmetic operation.

The following are the list of arithmetic operators:

The following example uses the arithmetic operators:

Comparison operators allow you to compare two operands.

A comparison operator returns a Boolean value, either true or false . If the comparison is truthful, the comparison operator returns true , otherwise, it returns false .

The following are the list of comparison operators in PHP:

Logical operators allow you to construct logical expressions. A logical operator returns a Boolean value.

PHP provides the following logical operators:

Bitwise operators perform operations on the binary representation of the operands. The following illustrates bitwise operators in PHP:

Incrementing/ Decrementing Operators

Increment (++) and decrement (–) operators give you a quick way to increase and decrease the value of a variable by 1.

The following table illustrates the increment and decrement operators:

Concatenating Operator

Concatenating operator (.) allows you to combine two strings into one. It appends the second string to the first one and returns the combined string. For example:

Assignment operator ( = ) assigns a value to a variable and returns a value. The operand on the left is always a variable, while the operand on the right can be a literal value, variable, expression, or a function call that returns a value. For example:

In the first expression, we assigned $x variable value 10 . In the second one, we assigned the value of $x to $y variable. The third one is a little bit complicated. First, we assigned 20 to $x . The assignment operator ( = ) returns 20 and then 20 is assigned to $z variable.

Besides the basic assignment operator( = ), PHP provides you with some assignment operators:

plus-equal +=
minus-equal -=
divide-equal /=
multiplication-equal *=
modulus-equal %=
XOR-equal ^=
AND-equal &=
OR-equal |=
concatenate-equal .=

PHP operators precedence

The precedence of an operator decides which order the operator is evaluated in an expression.

PHP assigned each operator precedence. Some operators have the same precedence, e.g., precedences of the addition ( + ) and subtraction( - ) are equal.

However, some operators have higher precedence than others.

For example, the precedence of the multiplication operator ( * ) is higher than the precedence of the add( + ) and the subtract ( - ) operators:

Because the precedence of the multiplication operator ( * ) is higher than the precedence of the add( + ) operator, PHP evaluates the multiplication operator ( * ) first and then add operator ( * ) second.

To force the evaluation in a particular order, you put the expression inside parentheses () , for example:

In this tutorial, you have briefly learned about the most commonly used PHP operators.

PHP Expressions and Operators

Operators are used to perform operations on variables and values. When we’re talking about operators we’re basically talking about “math”. By operator I mean things like multiplication and division signs.

As you might imagine there are tons of operators. Certainly enough to get lost in. The reality is, a lot of these you won’t use on a regular basis or they’ll make more sense if we cover them in a different lesson.

PHP Operators can be separated into the following categories:

PHP Arithmetic Operators

Php assignment operators, php incrementing / decrementing operators, php comparison operators, php logical operators.

Bitwise Operators

PHP Array Operators

PHP String Operators

An operator is something that takes one or more values (or expressions, in programming jargon) and yields another value (so that the construction itself becomes an expression).

Operator Precedence

The precedence of an operator specifies how “tightly” it binds two expressions together. For example, in the expression 1 + 5 * 3 , the answer is 16 and not 18 because the multiplication (“*”) operator has a higher precedence than the addition (“+”) operator. Parentheses may be used to force precedence, if necessary. For instance: (1 + 5) * 3 evaluates to 18 .

When operators have equal precedence their associativity decides how the operators are grouped. For example “-” is left-associative, so 1 – 2 – 3 is grouped as (1 – 2) – 3 and evaluates to -4 . “=” on the other hand is right-associative, so $a = $b = $c is grouped as $a = ($b = $c) .

Operators of equal precedence that are non-associative cannot be used next to each other, for example 1 < 2 > 1 is illegal in PHP. The expression 1 <= 1 == 1 on the other hand is legal, because the == operator has lesser precedence than the <= operator.

Although parentheses are not strictly needed, the readability of the code can often be increased by explicitly grouping rather than by using the implicit predominance and association of the operator.

The following table lists the operators in order of precedence, with the highest-precedence ones at the top. Operators on the same line have equal precedence, in which case associativity decides grouping.

The PHP arithmetic operators are used with numeric values to perform common arithmetical operations, such as addition, subtraction, multiplication etc.

The PHP assignment operators are used with numeric values to write a value to a variable.

The basic assignment operator in PHP is “=”. It means that the left operand gets set to the value of the assignment expression on the right.

The PHP increment operators are used to increment a variable’s value.

The PHP decrement operators are used to decrement a variable’s value.

The PHP comparison operators are used to compare two values (number or string):

Comparison operators, as their name implies, allow you to compare two values. You may also be interested in viewing the type comparison tables, as they show examples of various type related comparisons.

The PHP logical operators are used to combine conditional statements.

Bitwise Operator In PHP

The detailed illustrations of them are out of these lessons and just we introduce them and their names:

The PHP array operators are used to compare arrays.

String operators in PHP :

PHP has two operators that are specially designed for strings.

Operator Name Example Result. Concatenation $txt1 . $txt2 Concatenation of $txt1 and $txt2.=Concatenation assignment$txt1 .= $txt2Appends $txt2 to $txt1

PHP Operators: Understanding the Building Blocks of PHP Programming

As one of the most popular programming languages used on the web, PHP is a powerful tool for creating dynamic and interactive web applications. Whether you’re building a simple contact form or a complex content management system, understanding PHP operators is essential for writing efficient and effective code.

In this article, we’ll explore the different types of PHP operators and how they can be used to manipulate values, make comparisons, and control program flow. By the end of this article, you’ll have a comprehensive understanding of the building blocks of PHP programming .

What are Operators?

In programming, operators are special symbols or keywords that are used to perform specific actions on values or variables. In PHP, there are several different types of operators, each with their own set of rules and behaviors.

Operators can be used to perform mathematical operations, such as addition or subtraction, as well as comparison operations, such as checking if one value is equal to another. They can also be used to control program flow, such as executing code only if a certain condition is met.

Types of Operators

In PHP, there are several types of operators, each with its own set of rules and behaviors. Let’s take a closer look at each type.

Arithmetic Operators

Arithmetic operators are used to perform mathematical operations on values. PHP supports the following arithmetic operators:

Addition (+)
Subtraction (-)
Multiplication (*)
Division (/)
Modulus (%)
Exponentiation (**)

For example, the following code uses the addition operator to add two numbers:

Assignment Operators

Assignment operators are used to assign values to variables. In PHP, the following assignment operators are supported:

Assignment (=)
Addition assignment (+=)
Subtraction assignment (-=)
Multiplication assignment (*=)
Division assignment (/=)
Modulus assignment (%=)

For example, the following code uses the addition assignment operator to add a value to an existing variable:

Comparison Operators

Comparison operators are used to compare values and determine if they are equal, greater than, or less than each other. PHP supports the following comparison operators:

Not equal (!=)
Identical (===)
Not identical (!==)
Greater than (>)
Less than (<)
Greater than or equal to (>=)
Less than or equal to (<=)

For example, the following code uses the equal operator to check if two values are equal:

Logical Operators

Logical operators are used to combine multiple conditions and determine if they are true or false. PHP supports the following logical operators:

And (&&)

For example, the following code uses the and operator to check if two conditions are both true:

Increment and Decrement Operators

Increment and decrement operators are used to increase or decrease the value of a variable by one. PHP supports the following increment and decrement operators:

Increment (++)
Decrement (–)

For example, the following code uses the increment operator to increase the value of a variable by one:

String Operators

String operators are used to concatenate two or more strings together. In PHP, the concatenation operator is the period (.) symbol. For example, the following code uses the concatenation operator to concatenate two strings:

Array Operators

Array operators are used to manipulate arrays. PHP supports the following array operators:

Equality (==)
Identity (===)
Inequality (!=)
Non-identity (!==)

For example, the following code uses the union operator to combine two arrays:

Operator Precedence

When multiple operators are used in a single expression, the order in which they are evaluated is determined by their precedence. Operator precedence defines the order in which operators are evaluated in an expression.

For example, in the expression $a + $b * $c , the multiplication operator has a higher precedence than the addition operator. This means that $b * $c is evaluated first, and then the result is added to $a .

It’s important to understand operator precedence when writing complex expressions, as it can affect the outcome of the expression. To ensure that expressions are evaluated in the correct order, you can use parentheses to group sub-expressions.

In PHP programming, operators are essential for manipulating values, making comparisons, and controlling program flow. There are several types of operators in PHP, including arithmetic, assignment, comparison, logical, increment and decrement, string, and array operators.

By understanding the different types of operators and their behaviors, you can write more efficient and effective PHP code. It’s important to remember operator precedence when writing complex expressions, and to use parentheses to group sub-expressions to ensure that expressions are evaluated in the correct order.

Whether you’re a beginner or an experienced PHP programmer, understanding operators is a crucial part of building dynamic and interactive web applications. With this comprehensive guide to PHP operators, you’ll have the knowledge you need to take your PHP programming skills to the next level.

Conditional Operators

Conditional Assignment Operator in PHP is a shorthand operator that allow developers to assign values to variables based on certain conditions.

In this article, we will explore how the various Conditional Assignment Operators in PHP simplify code and make it more readable.

Let’s begin with the ternary operator.

Ternary Operator Syntax

The Conditional Operator in PHP, also known as the Ternary Operator, assigns values to variables based on a certain condition. It takes three operands: the condition, the value to be assigned if the condition is true, and the value to be assigned if the condition is false.

Here’s an example:

In this example, the condition is $score >= 60 . If this condition is true, the value of $result is “Pass”. Otherwise, the value of $result is “Fail”.

To learn more, visit the PHP ternary operator tutorial . Let’s now explore the section below to delve into the Null Coalescing Operator in PHP.

The Null Coalescing Operator (??)

The Null Coalescing Operator, also known as the Null Coalescing Assignment Operator, assigns a default value to a variable if it is null. The operator has two operands: the variable and the default value it assigns if the variable is null. Here’s an example:

So, In this example, if the $_GET['name'] variable is null, the value of $name is “Guest”. Otherwise, the value of $name is the value of $_GET['name'] .

Here’s another pattern utilizing it with the assignment operator. Let’s proceed.

The Null Coalescing Assignment Operator (??=)

The Null Coalescing Operator with Assignment, also known as the Null Coalescing Assignment Operator, assigns a default value to a variable if it is null. The operator has two operands: the variable and the default value it assigns if the variable is null. Here’s an example:

So, the value of $name is null. The Null Coalescing Assignment Operator assigns the value “Guest” to $name. Therefore, the output of the echo statement is “Welcome,”Guest!”.

Moving into the following section, you’ll learn how to use the Elvis operator in PHP.

The Elvis Operator (?:)

In another hand, The Elvis Operator is a shorthand version of the Ternary Operator. Which assigns a default value to a variable if it is null. It takes two operands: the variable and the default value to be assigned if the variable is null. Here’s an example:

In this example, if the $_GET['name'] variable is null, the value“Guest” $name s “Guest”. Otherwise, the value of $name is the value of $_GET['name'] .

Let’s summarize it.

Wrapping Up

The Conditional Assignment Operators in PHP provide developers with powerful tools to simplify code and make it more readable. You can use these operators to assign values to variables based on certain conditions, assign default values to variables if they are null, and perform shorthand versions of conditional statements. By using these operators, developers can write more efficient and elegant code.

PHP Operators

Operators are used to perform operations on variables and values.

PHP divides the operators in the following groups:

Arithmetic operators

Assignment operators.

Comparison operators
Increment/Decrement operators
Logical operators
String operators
Array operators

PHP Operators with Example

The PHP arithmetic operators are used with numeric values to perform common arithmetical operations, such as addition, subtraction, multiplication etc.

Operator Name Example Result
+ Addition $x + $y Sum of $x and $y
- Subtraction $x - $y Difference of $x and $y
* Multiplication $x * $y Product of $x and $y
/ Division $x / $y Quotient of $x and $y
% Modulus $x % $y Remainder of $x divided by $y
** Exponentiation $x ** $y Result of raising $x to the $y'th power (Introduced in PHP 5.6)

The PHP assignment operators are used with numeric values to write a value to a variable.

The basic assignment operator in PHP is "=" . It means that the left operand gets set to the value of the assignment expression on the right.

Assignment Same as… Description
x = y x = y The left operand gets set to the value of the expression on the right
x += y x = x + y Addition
x -= y x = x - y Subtraction
x *= y x = x * y Multiplication
x /= y x = x / y Division
x %= y x = x % y Modulus

Comparison Operators

The PHP comparison operators are used to compare two values (number or string):

== Equal $x == $y Returns true if $x is equal to $y
=== Identical $x === $y Returns true if $x is equal to $y, and they are of the same type
!= Not equal $x != $y Returns true if $x is not equal to $y
<> Not equal $x <> $y Returns true if $x is not equal to $y
!== Not identical $x !== $y Returns true if $x is not equal to $y , or they are not of the same type
> Greater than $x > $y Returns true if $x is greater than $y
< Less than $x < $y Returns true if $x is less than $y
>= Greater than or equal to $x >= $y Returns true if $x is greater than or equal to $y
<= Less than or equal to $x <= $y Returns true if $x is less than or equal to $y

Increment / Decrement Operators

The PHP decrement operators are used to decrement a variable’s value.

Operator Name Description
++$x Pre-increment Increments $x by one, then returns $x
$x++ Post-increment Returns $x, then increments $x by one
--$x Pre-decrement Decrements $x by one, then returns $x
$x-- Post-decrement Returns $x , then decrements $x by one

Logical Operators

The PHP logical operators are used to combine conditional statements.

and And $x and $y True if both $x and $y are true
or Or $x or $y True if either $x or $y is true
xor Xor $x xor $y True if either $x or $y is true, but not both
&& And $x && $y True if both $x and $y are true
|| Or $x || $y True if either $x or $y is true
! Not !$x True if $x is not true

String Operators

PHP has two operators that are specially designed for strings.

. Concatenation $txt1 . $txt2 Concatenation of $txt1 and $txt2
.= Concatenation assignment $txt1 .= $txt2 Appends $txt2 to $txt1

Array Operators

The PHP array operators are used to compare arrays.

+ Union $x + $y Union of $x and $y
== Equality $x == $y Returns true if $x and $y have the same key/value pairs
=== Identity $x === $y Returns true if $x and $y have the same key/value pairs in the same order and of the same types
!= Inequality $x != $y Returns true if $x is not equal to $y
<> Inequality $x <> $y Returns true if $x is not equal to $y
!== Non-identity $x !== $y Returns true if $x is not identical to $y
