Re: Upgrading php

The PHP_CompatInfo package simply evaluates a script to find which is the minimum version of PHP able to run it. Obviously it'll need updating for PHP 5.1, and it may well be a helpful tool for users deciding whether an upgrade is a good idea, but it's unlikely to be useful in the context under discussion. Andi was thinking of an auto-conversion tool for PHP 6 (something like autoconf's autoupdate) - this isn't something that's likely to be achievable in userspace code. - Steph ----- Original Message ----- From: "Eric Coleman" <eric@aplosmedia.com> To: "Steph Fox" <steph@zend.com> Cc: "Andi Gutmans" <andi@zend.com>; "Jani Taskinen" <sniper@iki.fi>; <truth@proposaltech.com>; <internals@lists.php.net> Sent: Sunday, November 20, 2005 4:34 AM Subject: Re: [PHP-DEV] Upgrading php > Im aware of that, but my thinking was to add the things in for > that....
