The call() magic function is to class functions what __get() is to class variables - if you call meow() on an object of class dog, PHP will fail to find the function and check whether you have defined a __call() function. If so, your __call() is used, with the name of the function you tried to call and the parameters you passed being passed in as parameters one and two respectively.

Here's an example of __call() in action:

class dog {

        public function
bark() {

// public function meow() {
            // print "Dogs don't meow!\n";
        // }

public function __call($function, $args) {
$args = implode(', ', $args);
"Call to $function() with args '$args' failed!\n";

$poppy = new dog;
$poppy->meow("foo", "bar", "baz");

Again, note that the meow() function is commented out - if you want to be sure that __call() is not used if the function already exists, remove the comments from meow().
