__call and recursion
in [General]

From: "Lawrance Shepstone" on 12 May 2010 06:49 Hi Daniel, Could you please tell us what version of PHP and OS you're using. The following code fragment runs as expected on my PHP 5.3.2/Windows/XP/32bit: <?php header('Content-Type: text/plain'); class A { private function method_a( $argument ) { echo('private method_a(\'' . $argument . '\') ...' . PHP_EOL ); } public function __call( $method, $arguments ) { if( method_exists( $this, $method ) && is_callable( array( $this, $method ) ) ) { call_user_func_array( array( $this, $method ), $arguments ); } else { echo('method \'' . $method . '\' either does not exist, or is not callable ...' . PHP_EOL ); } } } $a = new A(); $a->method_a('argument'); $a->method_b('argument'); ?> Results in: private method_a('argument') called ... method 'method_b' either does not exist, or is not callable ... Perhaps if you provided some code we could spot the problem. I would guess there's something fishy in your __call() method. Best of luck, Lawrance -----Original Message----- From: Richard Quadling [mailto:rquadling(a)googlemail.com] Sent: 12 May 2010 12:28 PM To: Daniel Kolbo Cc: PHP General Subject: Re: [PHP] __call and recursion On 9 May 2010 22:21, Daniel Kolbo <kolb0057(a)umn.edu> wrote: > Hello, > > I've defined a __call() method inside a class.

If not, calling call_user_func(array($this, $method), $args) will simply call the non-existent function. -- ----- Richard Quadling "Standing on the shoulders of some very clever giants!"
