#49203 [NEW]: call_user_func_array when calling a parent constructor not from a user class

From: magicaltux@php.net Operating system: Linux x86_64 PHP version: 5.3.0 PHP Bug Type: Scripting Engine problem Bug description: call_user_func_array when calling a parent constructor not from a user class Description: ------------ When using: call_user_func_array(array('parent', '__construct'), $var); This works if the parent is a user-defined class, but not if it's an extension-provided class (the extended constructor gets called twice). This is not easy to explain, see attached reproduce code for more details. My initial code was (in a class extending mysqli): private function __construct($params) { call_user_func_array(array('parent', '__construct'), $params); $this->set_charset('utf8'); } Using this instead awfully fixes the problem: parent::__construct($params[0], $params[1], $params[2], $params[3]); Note that this wasn't possible in PHP 5.2.x Warning: call_user_func_array(): First argument is expected to be a valid callback, 'parent::__construct' was given in foo.php on line 5 Reproduce code: --------------- <?php class B extends mysqli { public function __construct($var) { echo "here\n"; call_user_func_array(array('parent', '__construct'), $var); } } $x = new B(array('localhost', 'root')); Expected result: ---------------- here Actual result: -------------- here here Warning: call_user_func_array() expects parameter 2 to be array, string given in foo.php on line 6 -- Edit bug report at http://bugs.php.net/?id=49203&edit=1 -- Try a snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=49203&r=trysnapshot52 Try a snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=49203&r=trysnapshot53 Try a snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=49203&r=trysnapshot60 Fixed in SVN: http://bugs.php.net/fix.php?id=49203&r=fixed Fixed in SVN and need be documented: http://bugs.php.net/fix.php?id=49203&r=needdocs Fixed in release: http://bugs.php.net/fix.php?id=49203&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=49203&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=49203&r=needscript Try newer version: http://bugs.php.net/fix.php?id=49203&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=49203&r=support Expected behavior: http://bugs.php.net/fix.php?id=49203&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=49203&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=49203&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=49203&r=globals PHP 4 support discontinued: http://bugs.php.net/fix.php?id=49203&r=php4 Daylight Savings: http://bugs.php.net/fix.php?id=49203&r=dst IIS Stability: http://bugs.php.net/fix.php?id=49203&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=49203&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=49203&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=49203&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=49203&r=mysqlcfg
