How to downgrade from PHP 5.4 to 5.3

  • 772

Recently I upgraded PHP to 5.4, but it seems to be failing on me because APC isn't working with it, however this gave me no choice but to downgrade to 5.3, how can I do this?

I executed apt-get remove php5 and apt-get purge php5 then I removed the 5.4 repo from apt-get then executed apt-get install php5, it says it was installing 5.3, and I restarted php-fastcgi and php5-fpm but when I run php -v it says 5.4.

How can I downgrade from 5.4 to 5.3?

My server is running Ubuntu 11.04.

server apt php downgrade

  1. Downgrading PHP 5.4 to 5.3

    In Ubuntu downgrading process is a really mess. Here is the script which you could find it useful (it removes PHP 5.4 and install PHP 5.3):

    sudo apt-get remove --purge `dpkg -l | grep php | grep -w 5.4 | awk '{print $2}' | xargs`
sudo apt-get install php5=5.3.10-1ubuntu3.4 php5-cli=5.3.10-1ubuntu3.4 php5-common=5.3.10-1ubuntu3.4 libapache2-mod-php5=5.3.10-1ubuntu3.4
sudo apt-get install php5=5.3.10-1ubuntu3.4 php5-cli=5.3.10-1ubuntu3.4 php5-common=5.3.10-1ubuntu3.4 libapache2-mod-php5=5.3.10-1ubuntu3.4
sudo apt-get install php-pear=5.3.10-1ubuntu3.4 php5-curl=5.3.10-1ubuntu3.4 php5-gd=5.3.10-1ubuntu3.4 php5-intl=5.3.10-1ubuntu3.4 php5-mysql=5.3.10-1ubuntu3.4 php5-pspell=5.3.10-1ubuntu3.4 php5-recode=5.3.10-1ubuntu3.4 php5-snmp=5.3.10-1ubuntu3.4 php5-sqlite=5.3.10-1ubuntu3.4 php5-tidy=5.3.10-1ubuntu3.4 php5-xmlrpc=5.3.10-1ubuntu3.4 php5-xsl=5.3.10-1ubuntu3.4

    Where the available versions you can check by command: apt-cache showpkg php5

    After the installation, verify it by command: php --version

    Please be careful and don't install any other packages without package version specified (like php5-xcache), otherwise apt-get will replace your PHP instance with 5.4 again!

    To prevent this happening, you can hold these packages.

    Holding packages using dpkg

    To hold packages by dpkg, you can execute the following command:

    echo "php5 hold" | sudo dpkg --set-selections

    To hold all PHP packages, run the following command:

    dpkg --get-selections | grep ^php5 | sed s/install/hold/g | sudo dpkg --set-selections

    The following command will show you holding status of your php packages:

    sudo dpkg --get-selections | grep ^php

    Holding packages using aptitude

    You can also hold packages using aptitude e.g.:

    sudo aptitude hold php5

    Unhold:

    sudo aptitude unhold php5

  2. First execute apt-cache showpkg php5. There you will see version and other information about the package php5.

    To install a specific version run apt-get install <package name>=<version>

    In my Ubuntu 11.10 it would be apt-get install php5=5.3.6-13ubuntu3.6

  3. Maybe this guide will help you: How to downgrade a package in Ubuntu

    So to download and install any package of any available version you have to do this:

    sudo apt-get install Package=Version

  4. I had a similar problem.

    I removed the repositories.

    You have to remember that php -v runs the executable in the php-cli package so you have to remove that too.

    So I did the following to get back to 5.3.10:

    sudo apt-get remove php5-cli php5 php5-common
sudo apt-get install php5 php5-mysql php5-curl

    Now this should show the desired version:

    php -v

  5. from the steps you described, you forgot to apt-get update after purging php5.4 and removing the php5.4 repo.

    assuming you don't have the repo anymore in apt sources, if you run: 

    apt-get remove --purge php5 && apt-get update && apt-get install php5

    you should be back on 5.3
