This is such a nice Implementation and very useful, but i prefer to add the methods __toBool, __toInt and __toArray rather than __cast, stay tuned with PHP's other magic methods.. I dont agree fully with that post in feature request #38508 from helly. If that'll be the way, why did the decision for magic methods? Isnt that all complex although? ^^ We know, but in my eyes (and many others), i think that these magically stuff is one of the top key features for php. And none of these features will become critism i think. If not needed, just dont use them! The additional goody __toInvoke() introduced in 5_3 is a such nice addition for developing "quick gets" based on nested object sets: <?php $magazine(3)->getArticles(); // old way $magazine->getArticle($magazine->useMagazine(3)); ?> This helper is a "backdoor" like way to enable PHP to fully write nested Objects like in Javascript. And my opinion for that: I LIKE THIS :) I think this is a very very discussable topic to the changes for 5_3 or 6_0 beside the wanted support for traditional type hinting and utf8! thanks Previous Comments: ------------------------------------------------------------------------ [2008-11-23 09:01:02] mark at hell dot ne dot jp Please test the following extension : http://ookoo.org/svn/snip/phpcastable/ This extension adds a "Castable" interface. Any class implementing this interface have to implement a __cast() function. This function will be called when the object needs to be casted to a type. This extension is EXPERIMENTAL and needs more testing/review before being used in any production system. ------------------------------------------------------------------------ [2008-10-27 17:08:24] info at netmosfera dot it AWESOME! php developers, please, we need it!! http://bugs.php.net/bug.php?id=46404 ------------------------------------------------------------------------ [2008-10-06 04:15:03] mark at hell dot ne dot jp Backported to PHP 5.2.6 : http://ookoo.org/svn/snip/php-5.2.6_class_cast_func.patch ------------------------------------------------------------------------ [2008-10-05 16:33:07] 131 dot php at cloudyks dot org This is awesome ------------------------------------------------------------------------ [2008-10-05 08:49:55] mark at hell dot ne dot jp Did a test implementation only supporting a few types (int, float, bool, string). This works as expected. Test code: ---------- class test { public function __cast($type) { switch($type) { case 'string': return 'a string'; case 'bool': return true; case 'float': return 123.456; case 'int': return 978; default: var_dump($type); return null; } } } $t = new test(); var_dump((string)$t); var_dump((int)$t); var_dump((float)$t); var_dump((bool)$t); Result: string(8) "a string" int(978) float(123.456) bool(true) Here's the patch file for this simple implementation against PHP 5.3.0alpha2. http://ookoo.org/svn/snip/php-5.3.0alpha2_class_cast_func.patch ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
