This is now (almost) documented and can be seen here:

http://cvs.php.net/co.php/phpdoc/en/reference/var/functions/is-callable.xml

It's currently commented out as I'm not comfortable with these docs or
this topic. Please provide some more feedback :)

Please add a description of is_callable to the documentation. Here are
some rough notes about how what this function does.

This function wraps zend_is_callable. The first argument is the name
of a function or method. Class an 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);
        }

?>
