Upgrading PHP on Gentoo

Upgrading PHP

Gentoo's PHP herd have been making lots of changes to the PHP packages that are available in the Portage tree. These changes will give you access to the latest PHP4 and PHP5 packages as well as support for PECL and PEAR packages.

Some older packages are no longer supported, this includes dev-php/php, dev-php/php-cgi and dev-php/mod_php. These packages have all been rolled into one with the new dev-lang/php package, controlled by various USE flags. The older packages will be package masked at the end of March 2006 and removed from the tree one month after that.

To continue using PHP on Gentoo you should upgrade to dev-lang/php

You should follow the PHP Upgrade Guide for instructions on how to upgrade to the new packages. You can now also have a mixed PHP4 and PHP5 environment, instructions for doing so can be found here.

If you were using mod_php before you should build dev-lang/php with either the apache or apache2 USE flags, if you were using dev-php/php you should use the cli USE flag and if you were using php-cgi you should use the cgi and force-cgi-redirect USE flags. Other recommended USE flags can be found in the upgrade guide.

Support

You can get help with any PHP issues here on the forums, in the #gentoo-php IRC channel on irc.freenode.net or if you think you've found a bug please report it in Gentoo's Bugzilla.

Hi tomk,

UPDATE:

The PHP Herd announces that the old-style PHP packages, which were unsupported and deprecated for months, are finally going away.
After months of work, the team considers the new dev-lang/php package and the related dev-php[4,5]/ categories fully ready for production use, and encourage all users to upgrade.
Helpful informations can be found at the PHP project's pages, along with a HOWTO regarding the migration to dev-lang/php.
The old-style PHP packages (dev-php/php, dev-php/php-cgi, dev-php/mod_php, dev-php/PECL-*, and older dev-php/PEAR-* packages) will be package.masked on Wednesday, 19 April 2006, and removed from the Portage tree about a month later.

Thank god I found this thread. I had no idea why all the "old style" php packages were masked.

One thing the docs about upgrading php and using both php4 and php5 don't mention is what you should do if you only want php4 installed. Once the new php4 is installed, an "emerge world" will inevitably pull php5 in as well, and because of the way things are done, php5 becomes the default until such time as you set the default back to php4.

Creating (or editing) /etc/portage/package.mask to include the line

Hi All

I have a bunch of servers still running the old packages. I cannot unmerge them because they are masked, how then do I remove them?

I have tried to comment them out in /usr/portage/profile/packages.mask but portage still seems to think the package does not exist.

Should I instead just:
rm -rf /usr/lib/php4
rm -rf /usr/lib/php5
rm -rf /usr/lib/apache2/modules/libphp4.so

There's no need to unmask them, portage will let you unmerge a package that is masked.

I know it is installed:

Ok, well I can say with much embarrassment that it appears I have already removed these packages. Adding the -u flag to genlop makes all the difference:
