Using Dotdeb is very simple:

1. Add the main repository to your sources.list

Depending on your distribution (Wheezy or Squeeze), add these two lines to your /etc/apt/sources.list file (you can also choose a mirror near you) :

deb http://packages.dotdeb.org wheezy all
deb-src http://packages.dotdeb.org wheezy all

or

deb http://packages.dotdeb.org squeeze all
deb-src http://packages.dotdeb.org squeeze all

2. Options

If you want to install :

  • PHP 5.5 on Debian 7.0 “Wheezy”, add these two lines too :
    deb http://packages.dotdeb.org wheezy-php55 all
    deb-src http://packages.dotdeb.org wheezy-php55 all
  • PHP 5.4 on Debian 6.0 “Squeeze”, add these two lines too :
    deb http://packages.dotdeb.org squeeze-php54 all
    deb-src http://packages.dotdeb.org squeeze-php54 all

3. Fetch and install the GnuPG key

wget http://www.dotdeb.org/dotdeb.gpg
sudo apt-key add dotdeb.gpg

4. Enjoy

Run apt-get update. You should now be able to install the Dotdeb packages you want with apt-get (or dselect, or aptitude as well…)
