Alternatively, you can use a switch() statement: switch ($a){ case 1: echo '<p>$a == 1</p>'; break; case 2: echo '<p>$a == 2</p>'; break; case 3: echo '<p>$a == 3</p>'; break; default : echo '<p>$a == ' . $a . '</p>'; break; } The default: block activates when $a matches none of the case: blocks. Note the break at the end of each case block. If you don't use it, you'll get fallthrough, which can be useful sometimes (remove the breaks to see what I mean). if..elseif..else and switch..case..break..default are functionally equivalent. If you don't need fallthrough, which you use comes down to preference and readability.
