Re: PHP5 or PHP4 this is the question

You should get a new server that supports PHP 5.2.1. PHP 4 is dead. It hasn't had a non-security/bug release in years. PHP 5 is 3 years old. The one and only reason to care about PHP 4 at this point is if you're writing something that has to run on any possible cheap shared web host, and even many of those are starting to move to PHP 5.2. If you're on a shared host, get a new shared host that supports PHP 5.2. If you're running your own server, install PHP 5.2. If your server's sysadmin won't let you upgrade to 5.2 or won't give yo a new box on which to put 5.2, then get a new sysadmin because he is going to suffocate your development. As to the liklihood of portability, it depends on what you've actually done. Anything interesting with OO starts in PHP 5, but you said you're not using that. Are you passing objects (even stdClass objects)? That changes. Are you using any of the newer array handling functions, like array_combine? PHP 5 added a lot of them, many of which can be implemented in user-space using PEAR::PHP_Compat. There are more subtle differences, too. So it's quite possible that if you're not doing anything exotic you can downgrade your script without too much trouble. You're still better off doing the Internet a favor and removing one more PHP 4 server from existence. It will make your life easier in the long run.
