Ubuntu Lucid, Reverting PHP to 5.2
Ubuntu Lucid 10.04
I recently got an issue on PHP 5.3.2 via Ubuntu Lucid, after upgrading from Ubuntu 9.10 to Ubuntu 10.04, On one of the old Joomla! source I’m working on I keep getting this warning “Warning: Parameter 3 to showItem() expected to be a reference, value given in…. “.
The solution is downgrade your PHP 5.3.2 to PHP 5.2, here are the steps to follow.
1. On your /usr/local/sbin/, create php5_2-downgrade.sh, copy paste this source.

# 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.
Enter
sudo su
"
exit 1
fi
echo " OK";
# finish all apt-problems:
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:

" >> /etc/apt/sources.list.d/karmic.list
aptitude update
apache2ctl restart
echo install new from karmic:
aptitude -t karmic install $PHPLIST
# 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
2. Open your terminal, chmod +x /usr/local/sbin/php5.2-downgrade
3. On your terminal, ./php5_2-downgrade.sh
4. Just follow the steps, everything is very straight forward.
