note 83685 added to function.call-user-func-array

It appears that when PHP executes something like: $a = array(1,2,3); $b =& $a[1]; both $b and $a[1] are converted into references to a common value -- makes sense until you transfer that to a call_user_func: call_user_func_array('foo', $a); suddenly, inside foo, the second parameter is passed by reference! And you can't call this wrong, only another subtly of references. Note it appears that ksort($a) will remove the reference as well as put the elements in key order so you (probably) get what you expect. (see below on the use of a foreach ($a as &v).) ---- Server IP: 209.41.74.194 Probable Submitter: 76.105.247.92 ---- Manual Page -- http://www.php.net/manual/en/function.call-user-func-array.php Edit -- https://master.php.net/note/edit/83685 Del: integrated -- https://master.php.net/note/delete/83685/integrated Del: useless -- https://master.php.net/note/delete/83685/useless Del: bad code -- https://master.php.net/note/delete/83685/bad+code Del: spam -- https://master.php.net/note/delete/83685/spam Del: non-english -- https://master.php.net/note/delete/83685/non-english Del: in docs -- https://master.php.net/note/delete/83685/in+docs Del: other reasons-- https://master.php.net/note/delete/83685 Reject -- https://master.php.net/note/reject/83685 Search -- https://master.php.net/manage/user-notes.php
