#19842 [Opn->Bgs]: is_object returns FALSE on Incomplete classes

ID: 19842 Updated by: iliaa@php.net Reported By: alan@akbkhome.com -Status: Open +Status: Bogus Bug Type: Scripting Engine problem Operating System: linux PHP Version: 4CVS-2002-10-10 New Comment: 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 It'll work flawlesly if you second script also contains the class defention ( class atest { var $t = 1; } ). Without it the class defenition, everything works properly with the exception of is_object, which is failing due to the class atest not being defined. Previous Comments: ------------------------------------------------------------------------ [2002-10-10 02:13:16] alan_k@php.net variable object variables also fail on incomplete classes: eg. (from the example below) $data = unserialize(file_get_contents('/tmp/test')); $key = 't'; var_dump($data->$key); // is blank. //however $ar = get_object_vars($data); echo $ar[$key]; // produces 1 ------------------------------------------------------------------------ [2002-10-10 01:55:22] alan@akbkhome.com Steps to reproduce a) generate a serialized class eg. class atest { var $t = 1; } $t = new atest; $fh = fopen('/tmp/test','w'); fwrite($fh,serialize($t)); fclose($fh); ---------------------- In another file $data = unserialize(file_get_contents('/tmp/test')); if (!is_object($data)) { echo "DATA is an ".gettype($b)."!\n"; } } ---- should output DATA is an object! It's on the verge of expected behaviour, but it would be nice if it worked :) ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=19842&edit=1
