    PHP Assignment Operators: Efficient Variable Assignments

    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

    Example: The left operand gets set to the value of the expression on the right

    Code: 

    

<!DOCTYPE html>
<html>
<body>

<?php
$x = 10;  
echo $x;
?>  

</body>
</html>

    Output:

    This will produce the following result 

    

10

    Example: Addition

    Code: 

    

<!DOCTYPE html>
<html>
<body>

<?php
$x = 20;  
$x += 100;

echo $x;
?>  

</body>
</html>

    Output:

    This will produce the following result 

    

120

    Example: Subtraction

    Code: 

    

<!DOCTYPE html>
<html>
<body>

<?php
$x = 50;
$x -= 30;

echo $x;
?>  

</body>
</html>

    Output:

    This will produce the following result 

    

20

    Example: Multiplication

    Code: 

    

<!DOCTYPE html>
<html>
<body>

<?php
$x = 10;  
$y = 6;

echo $x * $y;
?>  

</body>
</html>

    Output:

    This will produce the following result 

    

60

    Example: Division

    Code: 

    

<!DOCTYPE html>
<html>
<body>

<?php
$x = 10;
$x /= 5;

echo $x;
?>  

</body>
</html>

    Output:

    This will produce the following result 

    

2

    Example: Modulus

    Code: 

    

<!DOCTYPE html>
<html>
<body>

<?php
$x = 15;
$x %= 4;

echo $x;
?>  

</body>
</html>

    Output:

    This will produce the following result
