Time to remove PHP 4 Syntax?

[HallofFamer]

Well as of CJAX 5.5 I still see PHP 4 syntax like this:

class ajax{
function ajax($controller){
...
}
}

PHP 4 is way outdated and no modern software should be compensating for this old dinosaur. Dont you think its about time to move on, and remove all PHP 4 stuff in the next version? After all, the latest version is already made compatible with PHP 5.4, so its definitely getting there.

Strangely, I do see protected/private methods being used in the script, guess its not PHP 4 compatible after all. If so, this still does not explain the PHP 4 syntax I found lol.

There is no PHP4 support. Not all constructors or methods may have a public declaration. It is still PHP5, by default considered public.
