Useful example:
<?php
$my_array = array(0 =>"air", 1 => "water", 2=> "soil");
if(array_search('air', $my_array))
echo ' "air" is in $my_array';
else
echo ' "air" is NOT in $my_array';
//it echoes: "air" is NOT in $my_array
?>
The array_search function returns an index (or a key). If the index of the matched element is 0,
then you can't use this function in an if or while structure, because bool(0) == false.
