Operator Example Action+ $b = $a + 3; Adds values
- $b = $a - 3; Subtracts values
* $b = $a * 3; Multiplies values
/ $b = $a / 3; Divides values
% $b = $a % 3; Returns the modulus, or remainder
Example:
<HTML>
<HEAD>
<TITLE>Using Arithmetic Operators</TITLE>
</HEAD>
<BODY>
<?
$a = 85;
$b = 24;
echo "<P>Original value of \$a is $a and \$b is $b</P>";
$c = $a + $b;
echo "<P>Added \$a and \$b and got $c</P>";
$c = $a - $b;
echo "<P>Subtracted \$b from \$a and got $c</P>";
$c = $a * $b;
echo "<P>Multiplied \$a and \$b and got $c</P>";
$c = $a / $b;
echo "<P>Divided \$a by \$b and got $c</P>";
$c = $a % $b;
echo "<P>The modulus of \$a and \$b is $c</P>";
?>
