Question

Is there a magic method in PHP which is called each time another method is called? the __callStatic() and __call() magic methods seem to work only when the method doesn’t exist.

Answer 1

No. What you’re asking for is called “advice” or aspect oriented programming. I believe there are some experimental extensions to allow this in PHP, but nothing you’d want to use in production.

What you can do, is create a wrapper, that delegates all calls via __call. E.g.:

class Foo {
  function bar() {
    echo "Foo::bar\n";
  }
}
class AdviceWrapper {
  protected $subject;
  function __construct($subject) {
    $this->subject = $subject;
  }
  function __call($name, $args) {
    echo "Before $name\n";
    $result = call_user_func_array(array($this->subject, $name), $args);
    echo "After $name\n";
    return $result;
  }
}
$foo = new AdviceWrapper(new Foo());
$foo->bar();
