ps. this behaviour is observed in both 5.0.3 and 5.0.4 Previous Comments: ------------------------------------------------------------------------ [2005-04-01 08:33:13] john at carney dot id dot au I too had an issue with extract($GLOBALS,EXTR_REFS) in PHP4, but it was resolved and I haven't seen any problems again until today when I reorganised some code and suddenly I'm getting extract() problems again. I haven't got a simple script that reproduces the problem (yet), but the symptom I'm getting is when I pass a variable that is set to a definitely as a parameter to a function, null is being sent instead of the variable value. Commenting out the extract() fixes the problem (but breaks other code). ------------------------------------------------------------------------ [2005-03-15 01:00:36] php-bugs at lists dot php dot net No feedback was provided for this bug for over a week, so it is being suspended automatically.

In my test case, it caused COM("someobject") to always return null, and in another case it just caused some strange output of a "1" instead of the expected strings. I never had a problem in php 5.0.0 up to CVS snapshot php5.0-win32-200407301630. Commenting out extract($GLOBALS, EXTR_REFS) fixes all strange behavior. I had a similar problem in php 4 which I reported as bug id 25708. That bug was fixed and I never had a problem again until 5.0.1. Reproduce code: --------------- extract($GLOBALS, EXTR_REFS); $query = new COM("IXSSO.Query"); if(is_object($query) == false) { var_dump($query); print "Can't create IXSSO Query object."; exit(); } Expected result: ---------------- Nothing Actual result: -------------- PHP has encountered an Access Violation at 01D5F185 ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=31217&edit=1
