An alternative to downgrading is to install both versions in parallel: http://bernhardhaeussner.de/blog/89_Howto:_PHP5.3_parallel_zu_PHP5_installieren

1. find all installed packages

dpkg -l | grep -i php

1. remove them

apt-get remove <package>

1. add the lenny sources to /etc/apt/source.list

2. pin the version of php and of related packages by creating the following file

/etc/apt/preferences.d/php5

Package: libapache2-mod-php5 libapache2-mod-php5filter

Pin-Priority: 1001

Package: php5-suhosin

Simulate the installation

 apt-get install -s php5 libapache2-mod-php5 php5-cli php5-common php5-curl php5-gd php5-mcrypt php5-mysql php5-suhosin

if everything is OK run the real installation by skipping the -s option.

Otherwise check the broken packages with the following command and pin the needed version in apt-cache policy php5-suhosin

apt-cache policy <broken backage name> 

1. restart apache

/etc/init.d/apache restart
