2 Test key() function : usage variations - Pass different data types as $array_arg arg.
5 /* Prototype : mixed key(array $array_arg)
6 * Description: Return the key of the element currently pointed to by the internal array pointer
11 * Pass different data types as $array_arg argument to test behaviour of key()
