__call and recursion
in [General]

From: Daniel Kolbo on 9 May 2010 17:21 Hello, I've defined a __call() method inside a class. Within the __call() method (after testing that the method exists and is callable I am using: call_user_func_array(array($this,$method), $args); However, this seems to be an infinite loop (and is crashing my test apache server). How, could I still use the __call() method and avoid an infinite loop of calling? Thanks, dK `

Assuming that your __call() method was reached because no $method was defined, using call_user_func_array() to call $method on the same object is going to result in ... your __call() method getting called again. You need to map the $method to whichever class methods you *actually* want to call, instead of blindly trying to reissue the call.

Would be good to see the code checking availability of the method, to get some idea of the error.

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!"
