PHP Assignment Operators - Assignment Operators in PHP
PHP Assignment Operators
- PHP assignment operators are used to assign a value to a variable. They are the most common type of operator used in PHP.
- Examples include the "=" operator, which assigns a value to a variable, and the "+=" operator, which adds a value to the variable and assigns the result.
| Operator | Syntax | Operation |
|---|---|---|
| Assign (=) | $a = $b | Operand on the left obtains the value of the operand on the right |
| Add then Assign (+=) | $a += $b | Simple Addition same as $a = $a + $b |
| Subtract then Assign (-=) | $a -= $b | Simple subtraction same as $a = $a – $b |
| Multiply then Assign (*=) | $a *= $b | Simple product same as $x = $a * $b |
| Divide then Assign (quotient - /=) | $a /= $b | Simple division same as $x = $a / $b |
| Divide then Assign (remainder - %=) | $a %= $b | Simple division same as $x = $a % $b |
Sample Code
<?php
$b = 100;
echo $b, "<br>";
$b = 150;
$b += 200;
echo $b, "<br>";
$b = 25;
$b -= 10;
echo $b, "<br>";
$b = 10;
$b *= 20;
echo $b, "<br>";
$b = 200;
$b /= 5;
echo $b, "<br>";
$b = 500;
$b %= 5;
echo $b;
?>
