The if else Statement

Often you'd want to execute a statement if a certain condition is met, and a different statement if the condition is not met.
This is what else is for. else extends an if statement to execute a statement in case the expression in the if statement evaluates to FALSE.

Syntax:

if(expr)
    statement
else
    statement

Tthe following example would display a is greater than b if $a is greater than $b, and a is NOT greater than b otherwise:

Example:

<?php
    $a = 50;
    $b = 70;
    if ($a > $b)
        echo "a is greater than b";
    else
        echo "a is NOT greater than b";
?>
