[PHP-DOC] #20216 [NEW]: is_callable needs documentation From: leon <email protected>

Bug description: is_callable needs documentation

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);
        }

?>
