Install PHP 5.3 on Ubuntu Karmic Koala From Dotdeb Packages

| Comments

First up, add the dotdeb repository

Fire up vim and add the following 2 lines to /etc/apt/sources.list:

deb http://php53.dotdeb.org stable all
deb-src http://php53.dotdeb.org stable all

Now do a sudo apt-get update to update your packages. The next step may fail but give it a go anyway.

Use Aptitude to install the PHP 5.3 packages.

sudo aptitude install php5-cli php5-common php5-cgi php5-mysql php5-curl libapache2-mod-php5 php5-memcache php5-xdebug

If this goes through ok, well done! In my case I had dependency issues that could not be satisfied. The package libicu38 was needed but could not be found in the repos in my sources. I did a quick google and could see that libicu38 had been taken out of Karmic but was available in Jaunty security, so add that repo to the sources file:

deb http://security.ubuntu.com/ubuntu jaunty-security main

Now do a apt-get update and then:

sudo aptitude install libicu38

Now go back to the previous step and try to install the PHP 5.3 packages again, hopefully they should work now.

You can now try and see if php 5.3 is working, issue php -v at the command line and see if it works correctly, once working you’ll get:

PHP 5.3.1-0.dotdeb.1 with Suhosin-Patch (cli) (built: DecĀ  5 2009
20:08:29) Copyright (c) 1997-2009 The PHP GroupZend Engine v2.3.0, Copyright
(c) 1998-2009 Zend Technologies with Xdebug v2.0.5, Copyright (c) 2002-2008,
by Derick Rethans with Suhosin v0.9.29, Copyright (c) 2007, by SektionEins

In my case I had a couple of errors that needed fixing - PHP complained about a date setting and xdebug also shouted a bit. They were easily fixed.

Edit xdebug.ini.

Fire up vim and edit /etc/php5/conf.d/xdebug.ini, you need to change the extension line so it’s a zend_extension and maybe also set the full path to the xdebug.so file (depending on if you set your include path in php.ini):

zend_extension=/usr/lib/php5/20090626+lfs/xdebug.so

Edit php.ini.

vim /etc/php5/apache2/php.ini and find the line that starts with ;date.timezone and change it to:

date.timezone = Europe/London

To get xdebug to work correctly you need to enable html errors:

html_errors = On

Finally do a sudo apache2ctl restart and everything should be working!
