You're right, I'm not sure what I did wrong since I had a problem where array_key_exists returned true, while
<?php
$keys = array_keys( $array );
var_dump( in_array( 'key', $keys ) );
?>
returned false. (Which does the exact same thing) I probably either messed up the array, or the order in one of the array calls.
I rewrote the entire section where I had this problem (which was probably a good idea anyway), so I don't have any demonstration code.
