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
