You could also try {$this->writeFoo}() -- not certain about this (OOP is not my 
big thing), but worth a try.

Re: [PHP] add functions to a class

This will not work.

$this->bla();

This is a PHP Syntax and tries to get the Class method, PHP dont look for a 
variable name at all!

It seams me strange also, that you try this, you should create  the method for 
the class itself, or extend it.

But this shoul work:

class Test {
  function Test () {
   $funcName = 'writeFoo';
   $$funcName = create_function ('', 'echo ("foo.\n");');
   $writeFoo ();
   $writeFoo2 = $writeFoo;
   $writeFoo2 ();
   $this->writeFoo = $writeFoo;
   return call_user_func($this->writeFoo, 'arg1, arg2');
  }
}

[PHP] add functions to a class

[Kelsang Tsenle]

Hi all,

I tried to add functions to a class, but it doesn't seem to work. Here's 
an example:


writeFoo = $writeFoo;
  $this->writeFoo ();
 }
}

$test = new Test ();
?>

This outputs:
foo.
foo.
PHP Fatal error:  Call to undefined method Test::writeFoo() in 
/test.php on line 11



Both $writeFoo () and $writeFoo2 () are executed, so it principally 
works, but once used in the object, it doesn't work anymore.



Any idea how that is supposed to work?


Gratefully,
 Tsenle
