We MUST use PHP 5 to help it growing until it become the standard...
PHP 5 has been presented as a revolution, a lot of new features have been added and a lot of projects have been made. But only a small group of hosters seem interested in supporting PHP 5 on their web servers. It is not so useful to have a beautiful programming language to use if we can't apply it to production environments.
PHP5 has seen a pretty slow adoption rate so far, but according to some statistics, its usage has been picking up lately - even among hosting providers.
