Description: ------------ call_user_func() does not propagate the scope when used in calls between two classes that have no child-parent relation. When they have child-parent relation as described in this bug entry: http://bugs.php.net/bug.php?id=47402 it is fine. As it is put in the "Backward Incompatible Changes" here: http://www.php.net/manual/en/migration53.incompatible.php "The call_user_func() family of functions now propagate $this even if the callee is a parent class. ". I guess it has to do it for classes that have no relation as well (or if not so the direct call t2::some_method() should not do it either). As it is at the moment is inconsistent. P.S. As well I think a better explanation with an example in the docs should be added for "The call_user_func() family of functions now propagate $this even if the callee is a parent class.". It is not clear at all what it is about if one don't get onto the original bug entry: "http://bugs.php.net/bug.php?id=47402";. I didnt use the original 47402 entry as in fact it is not a bug. Test script: --------------- class t1 { public function __call($method,$args) { //call_user_func('t2::some_method',$args);//for PHP 5.3 call_user_func(array('t2','some_method'),$args); t2::some_method(); } public function existing_method() { //call_user_func('t2::some_method');//for PHP 5.3 call_user_func(array('t2','some_method')); t2::some_method(); } } class t2 { public function some_method() { print isset($this)?'yes':'no'; print PHP_EOL; } } $t1 = new t1; $t1->existing_method(); $t1->non_existing_method();//use overloading Expected result: ---------------- yes yes yes yes Actual result: -------------- no yes no yes -- Edit bug report at http://bugs.php.net/bug.php?id=51886&edit=1 -- Try a snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=51886&r=trysnapshot52 Try a snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=51886&r=trysnapshot53 Try a snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=51886&r=trysnapshot60 Fixed in SVN: http://bugs.php.net/fix.php?id=51886&r=fixed Fixed in SVN and need be documented: http://bugs.php.net/fix.php?id=51886&r=needdocs Fixed in release: http://bugs.php.net/fix.php?id=51886&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=51886&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=51886&r=needscript Try newer version: http://bugs.php.net/fix.php?id=51886&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=51886&r=support Expected behavior: http://bugs.php.net/fix.php?id=51886&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=51886&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=51886&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=51886&r=globals PHP 4 support discontinued: http://bugs.php.net/fix.php?id=51886&r=php4 Daylight Savings: http://bugs.php.net/fix.php?id=51886&r=dst IIS Stability: http://bugs.php.net/fix.php?id=51886&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=51886&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=51886&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=51886&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=51886&r=mysqlcfg
