Thank you for taking the time to write to us, but this is not a bug. Please double-check the documentation available at http://www.php.net/manual/ and the instructions on how to report a bug at http://bugs.php.net/how-to-report.php ArrayAccess objects don't work in array_*() functions. You may want to turn this report into a feature request? Previous Comments: ------------------------------------------------------------------------ [2005-10-13 06:56:36] tschundler at gmail dot com Description: ------------ Functions to test an array's content don't work consistently with ArrayAccess objects. In the example, the object will return TRUE a request for any key. But, array_key_exists always returns FALSE, seemingly testing nothing, when it should be using the offsetExists method. Additionally, isset() on an array will return FALSE if the value at that offset is NULL. But with an ArrayAccess object, it returns TRUE, using the offsetExists method. Reproduce code: --------------- class ArrayTest implements ArrayAccess { function offsetExists ($offset) {return TRUE;} function offsetGet ($offset) {return ($offset==0) ? NULL : $offset;} function offsetSet ($offset, $value) {} function offsetUnset ($offset) {} } echo "with ArrayAcces:\n"; $x=new ArrayTest(); var_dump(array_key_exists(0,$x)); var_dump(array_key_exists(1,$x)); var_dump(isset($x[0])); var_dump(isset($x[1])); echo "with array():\n"; $y=array(0=>NULL,1=>1); var_dump(array_key_exists(0,$y)); var_dump(array_key_exists(1,$y)); var_dump(isset($y[0])); var_dump(isset($y[1])); Expected result: ---------------- with ArrayAcces: bool(true) bool(true) bool(false) bool(true) with array(): bool(true) bool(true) bool(false) bool(true) Actual result: -------------- with ArrayAcces: bool(false) bool(false) bool(true) bool(true) with array(): bool(true) bool(true) bool(false) bool(true) ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=34849&edit=1
