The specification of this function is misleading.
<?php
$os = array("mac"=>"Mac", "NT", "Irix", "Linux");
if (in_array("mac", $os)) {
echo "Got mac";
}
// prints Got mac !!!
?>
in_array searches both values AND indexes IF it is not running in the strict mode!
Correct specification: Checks if a value or a key exists in an array. In the strict mode, checks if a value exists in an array.
