Re: array_key_exists BC break

But wouldn't be useful to at least accept objects implementing ArrayAccess? On 10/23/2008 23:40, Mark van der Velden wrote:

Hi! I notice that 5.3 differs from 5.2 in how array_key_exists treats objects. In 5.2, if the second parameter (array) is allowed to be object and HASH_OF is applied to it. However, in 5.3 it would produce a warning requiring an array if object passed to it. Was it intentional? Maybe the problem is deeper and is in zend_parse_arg_impl where it should allow objects for 'a' if we can have HASH_OF from them?

To my understanding, it's superseded by the function property_exists. Also notice the difference of argument order. As written here: http://docs.php.net/array_key_exists
