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
if(expr) statement else statement
Tthe following example would display a is greater than b if $a is greater than $b, and a is NOT greater than b otherwise:
<?php $a = 50; $b = 70; if ($a > $b) echo "a is greater than b"; else echo "a is NOT greater 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
