searching array keys?

[kydo76]

i was wondering if there's any kind of function included in php or anywhere out there that is like in_array() but searches the keys of an array instead of the values

i was thinking of using array_flip() but then using in_array to search but then i dun think that after searching the pointer stays at the found value

any help? please? hehe

Yes, it is array-key-exists() (http://www.php.net/manual/en/function.array-key-exists.php) ;)
