For versions later than 4.2.0, the check isset($key) won't work properly because the function
now returns false, which "isset". This change is missing in the Change Log!
So the right way to use the function is:
<?php
$key = array_search($needle, $array);
if ($key!==null&&$key!==false) {
...
}
?>
This example will work in both older and newer to 4.2.0 versions.
P.S.: My previous post where isset() is used won't work in newer versions.
