else
(PHP 4, PHP 5, PHP 7, PHP 8)
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 greater than b if $a is greater than $b, and a is NOT greater than b otherwise:
<?php if ($a > $b) { echo "a is greater than b"; } else { echo "a is NOT greater than b"; } ?>
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).
