If you are presently using the dotdeb repo for php5, you can upgrade to 5.4.1 by adding the following to your /etc/apt/sources.list

deb http://packages.dotdeb.org squeeze-php54 all
deb-src http://packages.dotdeb.org squeeze-php54 all
deb http://packages.dotdeb.org squeeze all
deb-src http://packages.dotdeb.org squeeze all

You should then do apt-get update, apt-get upgrade. If you get a message that some packages have been held back you should then type apt-get dist-upgrade.

Check your php installation by typing php -v. If you see errors, you probably need to comment out .ini files that are no longer used in the new version such as suhosin.ini.
