#20216 [Opn->Fbk]: is_callable needs documentation

ID: 20216 Updated by: philip@php.net Reported By: leon@leonatkinson.com -Status: Open +Status: Feedback Bug Type: Documentation problem Operating System: RH 7.3 PHP Version: 4CVS-2002-11-01 New Comment: 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 :) Previous Comments: ------------------------------------------------------------------------ [2002-11-01 16:53:24] leon@leonatkinson.com 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); } ?> ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=20216&edit=1
