Thank you to the kind author of this script!

# OK, here's how to do the Apt magic to get PHP packages from the precise repositories:
echo "Am I root?  "
if [ "$(whoami &2>/dev/null)" != "root" ] && [ "$(id -un &2>/dev/null)" != "root" ] ; then
echo "  NO!
Error: You must be root to run this script.
sudo su
exit 1
echo "  OK";
#install aptitude before, if you don`t have it:
apt-get update
apt-get install aptitude
# or if you prefer apt-get use:
# alias aptitude='apt-get'
# finish all apt-problems:
aptitude update
aptitude -f install
#apt-get -f install
# remove all your existing PHP packages. You can list them with dpkg -l| grep php
PHPLIST=$(for i in $(dpkg -l | grep php|awk '{ print $2 }' ); do echo $i; done)
echo these pachets will be removed: $PHPLIST 
# you need not to purge, if you have upgraded from precise:
aptitude remove $PHPLIST
# on a fresh install, you need purge:
# aptitude remove --purge $PHPLIST
#Create a file each in
#/etc/apt/preferences.d like this (call it for example /etc/apt/preferences.d/php5_2);
#Package: php5
#Pin: release a=precise
#Pin-Priority: 991
#The big problem is that wildcards don't work, so you will need one such stanza for
each PHP package you want to pull from precise:
echo ''>/etc/apt/preferences.d/php5_3
for i in $PHPLIST ; do echo "Package: $i
Pin: release a=precise
Pin-Priority: 991
">>/etc/apt/preferences.d/php5_3; done
echo "# needed sources vor php5.3:

aptitude update
apache2ctl restart
echo install new from precise:
aptitude -t precise install $PHPLIST
# at the end retry the modul libapache2-mod-php5 in case it didn't work the first time:
aptitude -t precise install libapache2-mod-php5
apache2ctl restart

The only caveat I can think of is that I had to reinstall xDebug after downgrading via this script, but that's a very small price to pay for the convenience it provides!
