#34690 [NEW]: call_user_func and scope resolution operator ( :: )
From: claudio dot frizziero at nereal dot com
Operating system: Linux (Fedora Core 4)
PHP version: 5.0.5
PHP Bug Type: Scripting Engine problem
Bug description: call_user_func and scope resolution operator ( :: )
Description:
------------
When I use call_user_func (and call_user_func_array, of course) inside a
method to call a method of another class I'm expecting it works like the
scope resolution operator.
If it is not a bug: is it possible to add a flag, or alternatively add two
similar function (i.e. call_user_func_Paamayim_Nekudotayim and
call_user_func_array_Paamayim_Nekudotayim 8), to avoid the eval
workaround?
Thank you!
Note: i'm using php 5.0.4, but I don't find any fix in the changelog to
5.0.5
Reproduce code:
---------------
class MyClass {
public $string = 'Hello!';
public function SayHello() {
call_user_func(array('OutputClass', 'WriteToOutput'));
//
}
public function SayHello2() {
OutputClass::WriteToOutput();
}
public function SayHello3($outputclass, $outputmethod) {
// $outputclass::$outputmethod(); // syntax not allowed, with or
without curly braces
eval($outputclass . '::' . $outputmethod . '();'); // it works, but
it's a workaround
}
}
class OutputClass {
public function WriteToOutput() {
echo ($this->string);
}
}
$a = new MyClass();
$a->SayHello(); // Fatal error: Using $this when not in object context
$a->SayHello2(); // it works (wow!)
$a->SayHello3('OutputClass', 'WriteToOutput'); // it works only using
eval
