# else

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`. For example, the following code would display `a is bigger than b` if $a is bigger than $b, and `a is NOT bigger than b` otherwise:

`<?php if ($a > $b) { echo "a is bigger than b"; } else { echo "a is NOT bigger than b"; } ?>`

The else statement is only executed if the if expression evaluated to `FALSE`, and if there were any elseif expressions - only if they evaluated to `FALSE` as well (see elseif).
