Basically, the summary of this bug is wrong and I guess that correct could be the changed one. I tested both problems in PHP 5.2.5 and 5.2.6-dev. This example shows the problem using methods as well. <?php class Test{ public function unshift(&$arr, $mix){ return array_unshift($arr, $mix); } } $instance = new Test; $arr = array(2, 3, 4); $ref = new ReflectionMethod('Test', 'unshift'); // WARNING $ref->invoke($instance, &$arr, 1); $ref->invokeArgs($instance, array(&$arr, 0)); var_dump($arr); // [0,1,2,3,4] // FATAL ERROR $ref->invoke($instance, $arr, 1); $ref->invokeArgs($instance, array($arr, 0)); var_dump($arr); exit; ?> Thanks for solving this problem. Kind Regards. ------------------------------------------------------------------------ [2008-02-18 09:46:58] andrea at 3site dot it Sorry, this is what I would like to be able to do: <?php $arr = array(2, 3, 4); $ref = new ReflectionFunction('array_unshift'); $ref->invoke($arr, 1); $ref->invokeArgs(array($arr, 1)); var_dump($arr); exit; ?> Without fatal errors, simply because if send by reference is deprecated, ReflectionFunction (... and I didn't test ReflectionMethod ...) should be able to manage correctly variables by references. This is another Fatal Error example: <?php function unshift(&$arr, $mix){ return array_unshift($arr, $mix); } $arr = array(2, 3, 4); $ref = new ReflectionFunction('unshift'); $ref->invoke($arr, 1); $ref->invokeArgs(array($arr, 1)); var_dump($arr); exit; ?> I hope these examples explain correctly where and what is the problem. Kind Regards ------------------------------------------------------------------------ [2008-02-18 09:42:17] andrea at 3site dot it 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 ------------------------------------------------------------------------ [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?
