PHP/Class/ call

__call( ) method is called if PHP fails to find the method

 
<?
    class Dog {
            public $Name;
            public function bark( ) {
                    print "Woof!\n";
            }
            public function __call($function, $args) {
                    $args = implode(", ", $args);
                    print "Call to $function( ) with args "$args" failed!\n";
            }
    }
    $poppy = new Dog;
    $poppy->meow("foo", "bar", "baz");
?>

Intercepting Method Calls with the __call() Method (PHP 5 Only)

 
<?php
function r( $item_array, $immediately=false ) {
  return "Registering<br />\n";
}
class Item {
  public $name = "item";
  public $price = 0;
  function __call( $method, $args ) {
    $bloggsfuncs = array ( "r");
    if ( in_array( $method, $bloggsfuncs ) ) {
      array_unshift( $args, get_object_vars( $this ) );
      return call_user_func( $method, $args );
    }
  }
}
$item = new Item();
print $item->r( true );
?>

Using the __call() Method

 
<?php
     class ParentClass {
          function __call($method, $params) {
               echo "The method $method doesn"t exist!\n";
          }
     }
     class ChildClass extends ParentClass {
          function myFunction() {
          }
     }
     $inst = new ChildClass();
     $inst->nonExistentFunction();
?>
