#40248 [Opn]: Undefined members with combined operators produce no warning

ID: 40248 Updated by: vrana@php.net Reported By: jontsa at amigaone dot cc Status: Open -Bug Type: Documentation problem +Bug Type: Class/Object related Operating System: Solaris PHP Version: 5.2.0 New Comment: If this incostitent and possibly-errors-hiding behavior should be documented as a feature it should be explained why PHP behaves this way. Please write down the reasons why this is the correct behavior. I provided two reasons why this is more bug than a feature. Previous Comments: ------------------------------------------------------------------------ [2007-08-17 13:37:23] jani@php.net Because it is. ------------------------------------------------------------------------ [2007-08-17 11:09:21] vrana@php.net Why this form of usage of undefined property should be considered as feature? ------------------------------------------------------------------------ [2007-05-10 20:40:29] sniper@php.net This is actually a feature. Can't seem to find where it's documented though so reclassifying. ------------------------------------------------------------------------ [2007-01-26 10:12:51] jontsa at amigaone dot cc Description: ------------ When using a combined operator like += or ++ on an undefined class member, it does not produce "undefined property" notice as expected. Tested with all errors enabled. Reproduce code: --------------- $a+=5; $b=new stdClass; $b->a+=5; Expected result: ---------------- Notice: Undefined variable: a Notice: Undefined property: stdClass::$a Actual result: -------------- Notice: Undefined variable: a ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=40248&edit=1
