ID: 17309 Updated by: bram@totalgsm.net Reported By: pmoor@netpeople.ch Status: Open Bug Type: Variables related Operating System: linux PHP Version: 4.2.1 New Comment: This might be a duplicate of: http://bugs.php.net/bug.php?id=17246 However, this test case is clearer. Previous Comments: ------------------------------------------------------------------------ [2002-07-05 11:32:05] bram@totalgsm.net A workaround might be using variable function name like $func_name = 'pass_by_reference'; $funcname($data); However this doesn't work if the $func_name is an array to call a user method (which is a flaw in PHP :( ) ------------------------------------------------------------------------ [2002-05-20 11:01:03] pmoor@netpeople.ch i've disabled the "call-time pass-by-reference" option in my configuration file. now, when trying to call_user_func a function with reference-parameters, it won't work, unless i call-time-pass-by-reference my parameters despite the warning. ( this bug might be related to bug #17246 ) here a small example: function pass_by_reference( &$param ) { $param[] = "another entry"; } $data = array( "a first entry" ); call_user_func( "pass_by_reference", $data ); var_dump($data); // $data contains only one element ( "a first entry" ) ( == unexpected behaviour ) $data = array( "a first entry" ); call_user_func( "pass_by_reference", &$data ); // Warning: Call-time pass-by-reference has been deprecated - argument passed by value; ... var_dump($data); // $data contains both elements ( "a first entry", "another entry" ) ( == expected behaviour ) ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=17309&edit=1
