#28016 [Asn]: is_resource() returns false for resources of type "Unknown"

ID: 28016 User updated by: php at ter dot dk Reported By: php at ter dot dk Status: Assigned Bug Type: Scripting Engine problem Operating System: * PHP Version: 4CVS, 5CVS (2004-04-16) Assigned To: derick New Comment: But will it solve the problem in my situation? After all, I do have a resource by hand, and would be pretty sad if other functions wouldn't recognize it as a resource. I do agree though that making gettype not return "resource" for a closed resource (since is_resource() already does that). I just don't like the idea that these functions might not recognize my resource at all. - Peter Brodersen Previous Comments: ------------------------------------------------------------------------ [2004-04-16 03:15:17] derick@php.net No, the fix was correct. Close() in this case destroyed the resource data in the variable, so it's no longer a resource anymore. I think the correct thing to do here is to make gettype() not show "resource" either. ------------------------------------------------------------------------ [2004-04-15 22:35:54] sniper@php.net Derick, IMO, the fix for bug #27822 was incorrect. Resource is still a resource even if it's closed.. Or you need to unset the variable with any 'close'.. :) ------------------------------------------------------------------------ [2004-04-15 21:15:58] php at ter dot dk Description: ------------ (version of PHP is 4.3.6, not 4.3.6RC3, but I wasn't able to select that) If a resource for some reason is of type "Unknown", is_resource() returns false. Though, gettype() still returns "resource" as type, as always. This behaviour in is_resource() has changed between 4.3.5 and 4.3.6. I'm guessing here, but the new behaviour could be related to changes introduced to fix bug 27822 (which was fixed in between 4.3.5 and 4.3.6). In my example I'm using php-imlib to gain an object of type "Unknown". Even though it isn't an official extension, there still is some inconsistency between gettype() returning "resource" and is_resource() returning false. In other words, it's the inconsistency between is_resource() and gettype() I see as the bug. Example is also available at: http://stock.ter.dk/resource_error.php Reproduce code: --------------- $i = imlib_create_image(100,200); var_dump($i); var_dump(gettype($i)); var_dump(is_resource($i)); Expected result: ---------------- resource(2) of type (Unknown) string(8) "resource" bool(true) Actual result: -------------- resource(2) of type (Unknown) string(8) "resource" bool(false) ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=28016&edit=1
