# `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).
