#30337 [Opn]: empty() does not return true on empty objects

ID: 30337 Updated by: nlopess@php.net Reported By: jorma dot tuomainen at softera dot fi Status: Open Bug Type: Documentation problem Operating System: Solaris PHP Version: 5.0.1 Assigned To: andi New Comment: I think that the empty() page deserves a little note about this. Can you please add this, Aidan? :) Previous Comments: ------------------------------------------------------------------------ [2004-10-25 08:39:41] aidan@php.net It's covered under http://php.net/migration5 Perhaps this deserves a note on the empty() page, perhaps not. ------------------------------------------------------------------------ [2004-10-23 16:15:27] tony2001@php.net "As far as the new OO model is concerned objects are always handles, they are always true and they aren't empty." (c) Andi Making it a documentation problem then. ------------------------------------------------------------------------ [2004-10-11 20:48:41] andrey@php.net <?php function empty_object($obj){ return count((array)$obj)==0; } class foo{var $a=1;} $std=new stdclass; $foo=new foo; var_dump(empty_object($obj), empty_object($foo)); ?> bool(true) bool(false) ------------------------------------------------------------------------ [2004-10-08 13:38:29] th at zirkonium dot net I find this bug pretty irritating too. In my opinion empty() shouldn't behave this way, or at least like Jorma said, it should be mentioned in docs or some other way to check if objects are empty. ------------------------------------------------------------------------ [2004-10-07 16:39:17] jorma dot tuomainen at softera dot fi No, I'm not using compatibility mode. If this is wanted behaviour it should least be mentioned in the documentation. I still don't understand why empty() have to behave that way. Since that makes perfectly good function for a good purpose go to waste on objects. Is there going to be some function for checking empty objects(no methods or properties) or do I need to implement that myself? ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
