I've updated from 9.10 to 10.04, but unfortunately the PHP provided with 10.04 is not yet supported by zend optimizer.

As far as I understand, I need to somehow replace the PHP 5.3 package provided under 10.04 with an older PHP 5.2 package provided under 9.10. However I'm not sure whether this is the right way to downgrade PHP and if yes, I don't know how to replace the 10.04 package with 9.10 package.

Could you please help me with that?

# OK, here's how to do the Apt magic to get PHP packages from the karmic 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 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 karmic:
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=karmic
#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 karmic:

echo ''>/etc/apt/preferences.d/php5_2
for i in $PHPLIST ; do echo "Package: $i
Pin: release a=karmic
Pin-Priority: 991
">>/etc/apt/preferences.d/php5_2; done

# duplicate your existing sources.list replacing lucid with karmic and save it in sources.list.d:
#sed s/lucid/karmic/g /etc/apt/sources.list | sudo tee /etc/apt/sources.list.d/karmic.list

# better exactly only the needed sources, cause otherwise you can get a cachsize problem:
echo "# needed sources vor php5.2:

# at the end retry the modul libapache2-mod-php5 in case it didn't work the first time:
aptitude -t karmic install libapache2-mod-php5

apache2ctl restart
