ID: 53081 Comment by: andy at andy-burton dot co dot uk Reported by: giorgio dot liscio at email dot it Summary: why you should bring back abstract static methods Status: Bogus Type: Feature/Change Request Package: Class/Object related PHP Version: 5.3.3 Block user comment: N Private report: N New Comment: Still get strict warning in 5.3.2 - static abstract classes in 5.3 make perfect sense to me, no idea why this is flagged as bogus!

I just wish the bug handlers wouldn't be so rude as to flag valid reports as bogus when users spend effort to report these bugs with examples. There's nothing bad about having abstract static methods in a language that finally supports static inheritance (since PHP 5.3). This is normal practice in other languages too so E_STRICT shouldn't be emitted. ------------------------------------------------------------------------ [2010-10-17 02:56:08] giorgio dot liscio at email dot it simplified case abstract class AFSItem { public static function getIfValid ($fullPath) { // i use static::isValid to get the method defined in the called class if(static::isValid($fullPath)) return new static($fullPath); } protected function __construct ($fp){} // i want to force real classes to implement a way to check a path before instance an object protected abstract static function isValid ($fullPath); // abstract declaration } class File extends AFSItem { protected static function isValid ($fullPath) // implementation { return is_file($fullPath); } } class Dir extends AFSItem { protected static function isValid ($fullPath) // implementation { return is_dir($fullPath); } } class Image extends File { protected static function isValid ($fullPath) // implementation with override { if(parent::isValid($fullPath) AND (bool)getimagesize($fullPath)) return true; return false; } } ------------------------------------------------------------------------ [2010-10-17 02:03:36] cmanley at xs4all dot nl This bug (emitting E_STRICT for abstract static methods in PHP 5.3 while static inheritance has finally been implemented) leads to another bug that I recently submitted: http://bugs.php.net/bug.php?id=53086 These are definately different bugs, but this bug spawns the other one which is more catestrophic. If you don't see the bug, then add E_STRICT to your error reporting: error_reporting(E_ALL | E_STRICT); ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
