Searching through an array

If I need to check if a variable could be one of many, rather than use the clunky method of multiple conditions:


if ($variable == "this" OR $variable == "that" OR $variable == "those")

I find it more elegant to place all the variables in an array then search the array:


<?php

$listofitems = array("this", "that", "those");

if (in_array($variable, $listofitems))

?>

Note - in_array returns a 1 if found, a 0 if not found. I used to use array_search which returns the index of the found item but that always gave a negative result if the found item was the first item in the array (eg - with index 0).
