I had been frustrated with the state of Edgy’s php packages. I have been developing on 5.2.0 since attending the 2006 Zend Conference. I could have built everything myself, but I have been looking for an easy way to maintain the server. I can always move to a custom compiled server if it becomes necessary. Also, I haven’t seen backports for Feisty yet.
The installation is very easy:
Edit /etc/apt/sources.list to include
deb http://packages.dotdeb.org stable all
deb-src http://packages.dotdeb.org stable all
then just run
# apt-get update
# apt-get upgrade
you will have to consent to unsigned packages. You should now have updated PHP packages.
