PHP: If else

This entry is part 25 of 54 in the series PHP Tutorial

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:


$a = 10;
$b = 20;

if ($a > $b) {
  echo "a is greater than b";
} else {
  echo "a is NOT greater than b";
