Table

Example
Example PHP Program to show the operators in action.
<?php
// declare two variables a and b
$a = 11;
$b = 3;
//Perform operations
$sum = $a + $b;
$diff = $a – $b;
$product = $a * $b;
$div = $a / $b;
$mod = $a % $b;
//Output
echo “Addition is “.$sum;
echo “<br>”;
echo “Subtraction is “.$diff;
echo “<br>”;
echo “Multiplication is “.$product;
echo “<br>”;
echo “Division is “.$div;
echo “<br>”;
echo “Remainder is “.$mod;
?>
