#18926 [Opn->Fbk]: call_user_func_array does not mirror normal scope inside class functions

ID: 18926 Updated by: kalowsky@php.net Reported By: tater@potatoe.com -Status: Open +Status: Feedback Bug Type: Scripting Engine problem Operating System: Mac OS X 10.1.5 / Darwin 5.5 PHP Version: 4CVS-2002-08-15 New Comment: can you please give a ZE example? Previous Comments: ------------------------------------------------------------------------ [2002-08-15 20:26:30] tater@potatoe.com You see the same behavior with PHP 4.3.0-dev and ZE1.3 for 'parent'. Calls to 'self' and the change in function name scope are ZE2 only features anyway (I think). ------------------------------------------------------------------------ [2002-08-15 20:09:25] kalowsky@php.net Is this with ZE2 or ZE1? ------------------------------------------------------------------------ [2002-08-15 17:10:04] tater@potatoe.com Using call_user_func_array() inside a class function produces different results from the equivalent direct function calls. call_user_func_array(array('self,'method'), $args) gives an error, although self::method() works, as does call_user_func_array(array('myclassname','method'), $args). (This format for calling static class methods is undocumented, by the way - is it officially even supposed to work?) Also, in PHP 4.3-dev, a call to myfunction() inside a class function will check the current class's function table first, before calling a globally defined function. But call_user_func_array('myfunction',$args) does not - it only looks for global functions. Whether any of these things are bugs or features, I don't know. test script: <?php class foo { function myname() { return 'foo'; } function myself() { $args = func_get_args(); echo '<li>', self::myname(), '::myself - my args are ',var_export($args,TRUE),"\n"; } } class bar extends foo { function myname() { return 'bar'; } function test() { foo::myself('calling foo::myself'); bar::myself('calling bar::myself'); self::myself('calling self::myself'); parent::myself('calling parent::myself'); call_user_func_array(array('foo','myself'), array('call_user_func_array on array("foo","myself")')); call_user_func_array(array('bar','myself'), array('call_user_func_array on array("bar","myself")')); call_user_func_array(array('parent','myself'), array('call_user_func_array on array("parent","myself")')); call_user_func_array(array('self','myself'), array('call_user_func_array on array("self","myself")')); myself('calling myself'); call_user_func_array('myself', array('call_user_func_array on "myself"')); } } function myself() { echo '<li>i am the external function myself - my args are ', var_export(func_get_args(), TRUE), "\n"; } bar::test('testing',1,2); ?> ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=18926&edit=1
