is_callable & Bug 20216

Can someone shed some light on is_callable? I think I understand it's meant for testing whether a function or method is callable, but it would be nice to get some confirmation from someone who knows for sure. Philip and I are trying to add this function to the manual. Here are some rough notes I have on my understanding of the function (from http://bugs.php.net/bug.php?id=20216): This function wraps zend_is_callable. The first argument is the name of a function or method. Class and object methods are specified by passing an array with two elements: class or object and method name. The second argument seems to be for checking syntax only, but I can't figure out how to make is_callable return FALSE when the second argument is TRUE. The third argument receives the "callable name". In the example below it's "a::b". Note, however, that despite the implication that a::b() is a callable static method, this is not the case. <? class a { var $c; function b() { return($this->c); } } $d = new a; if(is_callable(array($d, 'b'), FALSE, $name)) { print($name); } ?> Thanks! --- Leon Atkinson <http://www.leonatkinson.com/>
