| Late static binding | Sami Samhuri | 19th July, 2006 | 2006-07-19T10:23:00-07:00 | php, coding, coding, php |
Update: This has been discussed and will be uh, sort of fixed, in PHP6. You'll be able to use static::my_method() to get the real reference to self in class methods. Not optimal, but still a solution I guess.
As colder on ##php (freenode) told me today, class methods in PHP don't have what they call late static binding. What's that? It means that this code:
class Foo
{
public static function my_method()
{
echo "I'm a " . get_class() . "!\n";
}
}
class Bar extends Foo
{}
Bar::my_method();
outputs "I'm a Foo!", instead of "I'm a Bar!". That's not fun.
Using CLASS in place of get_class() makes zero difference. You end up with proxy methods in each subclass of Foo that pass in the real name of the calling class, which sucks.
class Bar extends Foo
{
public static function my_method()
{
return parent::my_method( get_class() );
}
}
I was told that they had a discussion about this on the internal PHP list, so at least they're thinking about this stuff. Too bad PHP5 doesn't have it. I guess I should just be glad I won't be maintaining this code.
The resident PHP coder said "just make your code simpler", which is what I was trying to do by removing duplication. Too bad that plan sort of backfired. I guess odd things like this are where PHP starts to show that OO was tacked on as an after-thought.
