else(PHP 4, PHP 5, PHP 7)
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).
