Previous Comments: ------------------------------------------------------------------------ [2003-09-29 09:29:07] ask-me at ask-me dot ru Description: ------------ Unfortunatly even in version 4.3.3 there was an bug with "call_user_func_array" function. call_user_func and call_user_func do respect functions that return references. That is, function foo that returns a references to an object, does not return a reference to an object when foo is called via call_user_func. Instead, foo called via call_user_func returns a "copy" of the object. (I'm not sure "copy" is the right word.) See the code example for a concise example of the problem. Reproduce code: --------------- function &testfunction() { global $testglobal; return ($testglobal=1); } $testglobal_link=&call_user_func_array("testfunction",array('testparam-1','testparam-2')); // $testglobal_link must be link to $testglobal at this stage print $testglobal_link; // trying to assign new value to $testglobal thru link $testglobal_link=2; // in theory we will get "2" as result print $testglobal; // but unfortunatly we will have "1" as result print $testglobal_link; ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=25690&edit=1
