Felipe, I'm testing PHP Version 5.2.6-dev and I have the same problem. <?php $arr = array(2, 3, 4); $ref = new ReflectionFunction('array_unshift'); $ref->invoke(&$arr, 1); $ref->invokeArgs(array(&$arr, 1)); var_dump($arr); exit; ?> Warning: Call-time pass-by-reference has been deprecated; If you would like to pass it by reference, modify the declaration of [runtime function name](). If you would like to enable call-time pass-by-reference, you can set allow_call_time_pass_reference to true in your INI file in ... I guess above warning should not exists. So, can you confirm that this is a bug? Cheers Previous Comments: ------------------------------------------------------------------------ [2008-02-17 23:41:00] [EMAIL PROTECTED] $ref->invoke(&$arr, 1); $ref->invokeArgs(array(&$arr, 0)); var_dump($arr); // correct and expected result Doesn't show warning on 5.2.6 and 5.3. That was my message. ------------------------------------------------------------------------ [2008-02-17 23:17:39] andrea at 3site dot it Hi Felipe, I don't understand your messages. I know that it generates a Fatal error as I know that send the array forcing reference works as expected but it generates a warning. As I wrote on php.net manual too, to solve this strange behaviour I used a "non-sense" strategy (at least for me) ... $arr = array(2, 3, 4); $ref = new ReflectionFunction('array_unshift'); $ref->invokeArgs(array_merge(array(&$arr), array(1))); $ref->invokeArgs(array_merge(array(&$arr), array(0))); // $arr == [0,1,2,3,4] I can't understand why one single value is accepted by reference inside an array while more than one is not accepted. Since PHP 5 should manage by itself references I think that ReflectionFunction should do the same, without reference requirement but working as expected. Do you think am I wrong? Kind Regards ------------------------------------------------------------------------ [2008-02-17 19:45:57] [EMAIL PROTECTED] Ops... 5_3 also issued 'Fatal error'. Warning: Parameter 1 to array_unshift() expected to be a reference, value given in %s on line %d Fatal error: Uncaught exception 'ReflectionException' with message 'Invocation of function array_unshift() failed' in %s:%d Stack trace: #0 %s(19): ReflectionFunction->invoke(Array, 1) #1 {main} thrown in %s on line %d ------------------------------------------------------------------------ [2008-02-17 19:40:54] [EMAIL PROTECTED] PHP 5.2.6: $ref->invoke($arr, 1); Fatal error: Uncaught exception 'ReflectionException' with message 'Invocation of function array_unshift() failed' $ref->invokeArgs(array($arr, 0)); Fatal error: Uncaught exception 'ReflectionException' with message 'Invocation of function array_unshift() failed' PHP 5.3.0: $ref->invoke($arr, 1); and $ref->invokeArgs(array($arr, 0)); Warning: Parameter 1 to array_unshift() expected to be a reference, value given ------------------------------------------------------------------------ [2008-02-17 00:06:41] andrea at 3site dot it Description: ------------ For some reason, ReflectionFunction doesn't allow me to to invoke a basic function like, for example, array_unshift. Reproduce code: --------------- $arr = array(2, 3, 4); /** EXPECTED RESULT * array_unshift($arr, 1); * array_unshift($arr, 0); * var_dump($arr); // 0, 1, 2, 3, 4 */ $ref = new ReflectionFunction('array_unshift'); // WARNING: Call-time pass-by-reference has been deprecated $ref->invoke(&$arr, 1); $ref->invokeArgs(array(&$arr, 0)); var_dump($arr); // correct and expected result // FATAL ERROR - Uncaught exception 'ReflectionException' with message 'Invocation of function array_unshift() failed' $ref->invoke($arr, 1); $ref->invokeArgs(array($arr, 0)); var_dump($arr); // nothing, because of fatal error ... exit; Expected result: ---------------- I would like to do what I'm trying to do without errors. I mean both fatal and warning. Actual result: -------------- An illogical problem for a simple operation. You have a "passed by reference" in your core but you choosed to disable send by reference in PHP ... and ReflectionFunction doesn't seem to be able to manage this kind of "situation". Please do not reply with something like: change your PHP configuration ... I would like to write not deprecated code. Thank You. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=44139&edit=1
