There are following arithmatic operators supported by PHP language:
Assume variable A holds 10 and variable B holds 20 then:
| Operator | Description | Example |
|---|---|---|
| + | Adds two operands | A + B will give 30 |
| – | Subtracts second operand from the first | A – B will give -10 |
| * | Multiply both operands | A * B will give 200 |
| / | Divide numerator by denumerator | B / A will give 2 |
| % | Modulus Operator and remainder of after an integer division | B % A will give 0 |
| ++ | Increment operator, increases integer value by one | A++ will give 11 |
| — | Decrement operator, decreases integer value by one | A– will give 9 |
PHP Arithmatic Operators Example
<html>
<head><title>Arithmetical Operators</title><head>
<body>
<?php
$a = 42;
$b = 20;
$c = $a + $b;
echo "Addtion Operation Result: $c <br/>";
$c = $a - $b;
echo "Substraction Operation Result: $c <br/>";
$c = $a * $b;
echo "Multiplication Operation Result: $c <br/>";
$c = $a / $b;
echo "Division Operation Result: $c <br/>";
$c = $a % $b;
echo "Modulus Operation Result: $c <br/>";
$c = $a++;
echo "Increment Operation Result: $c <br/>";
$c = $a--;
echo "Decrement Operation Result: $c <br/>";
?>
</body>
</html>
This will produce following result
Addtion Operation Result: 62 Substraction Operation Result: 22 Multiplication Operation Result: 840 Division Operation Result: 2.1 Modulus Operation Result: 2 Increment Operation Result: 42 Decrement Operation Result: 43
