My question is not if it is a bug or not a bug, my question is to
resolve the problem. The problem is that I MUST use the "eval" - a
dirty workaround - because:
- php parser doesn't accept :: operator and 2 vars (but it doesn't
matters, because I can't pass a dynamic number of arguments)
- call_user_func (and call_user_func_array) calls the function in a way
that doesn't have an equivalent in the PHP syntax (both $class->method()
and $class::method() work in two different way - the first will see
$this of its class, the second will see $this of the class where it is
called)
If i'm not explained, tell me and I'll make some examples...

There is no $this when you call a static method.
The error message clearly says that.

Expected result:
to see "Hello!" on my browser (or console) when I call $a->SayHello();
Actual result:
Fatal error: Using $this when not in object
You don't get the problem? What do you get? 3 "Hello!"?

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
