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).
