ID: 54003 Comment by: jon at langevin dot me Reported by: giorgio dot liscio at email dot it Summary: re-enable abstract static methods Status: Open Type: Feature/Change Request Package: Class/Object related PHP Version: 5.3.5 Block user comment: N Private report: N New Comment: Valid issue, please consider. In this related submission, Rasmus even agreed that the expected behavior is correct, but he didn't answer why PHP E_STRICT reports an error for abstract static method declaration. :: https://bugs.php.net/bug.php?id=53081 When accessed via static::method(), this is a very valid programming approach.

Use normal inheritance instead. 3. WONTFIX ------------------------------------------------------------------------ [2012-03-06 04:19:14] cgili at yahoo dot com Inheritance and method override is something really important on PHP, it's important to redefine not only the methods but also the parameters they take, for instance, you have a class Rectangle with a method called Area that calculates the area in m2 by requiring the height and width, now you want to create a Cube class extending the Rectangle class, and override the function Area to calculate the area in cubic meters, the formula is different and the parameters are 3, height, width and deep. It's the very "BASIC" definition of Class inheritance and Method Overriding. ------------------------------------------------------------------------ [2011-02-13 00:14:32] giorgio dot liscio at email dot it Description: ------------ hi, please read carefully my request before trash this since static inheritance is now implemented in php, enabling this again can provide an awesome natural feature of the language I talked with some php hackers, and they agree with me, but in past, I did not have good news about this: I'm sure my example makes totally sense, and this should stay disabled only if there are technical limitations that do not matter with the good logic of my example in practice, I can understand WONT FIX, but not BOGUS abstract class AFileSystemItem { 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 ($fullPath); // abstract declaration } class Dir extends AFileSystemItem { protected static function isValid ($fullPath) // implementation { return is_dir($fullPath); } } class File extends AFileSystemItem { protected static function isValid ($fullPath) // implementation { return is_file($fullPath); } } class Image extends File { protected static function isValid ($fullPath) // implementation with override { if(parent::isValid($fullPath) AND (bool)getimagesize($fullPath)) return true; return false; } } ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=54003&edit=1
