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!

Georgio,
Your example makes perfect sense. 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.

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;
}
}

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);
