install PHP 5.3.1 on ubuntu 9.10

PHP 5.3.1 is a requirement if you want to test Symfony2 alpha :

And there is a demo available on my github:

http://github.com/docteurklein/symfony2-tests


Here we go:

add this deb repository in your /etc/apt/sources.list:

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

then :

sudo apt-get update && apt-get upgrade


then: ( if it's already installed )

sudo apt-get remove libapache2-mod-php5 php-pear php5 php5-cli php5-common php5-curl php5-gd php5-memcache php5-mysql php5-xdebug php5-apc php5-mcrypt

then:

sudo apt-get install libapache2-mod-php5 php-pear php5 php5-cli php5-common php5-curl php5-gd php5-memcache php5-mysql php5-xdebug php5-apc php5-mcrypt


if some dependencies cannot be installed, do it manually :

wget http://security.ubuntu.com/ubuntu/pool/main/i/icu/libicu38_3.8.1-2ubuntu0.2_i386.deb

sudo dpkg -i libicu38_3.8.1-2ubuntu0.2_i386.deb


wget http://fr.archive.ubuntu.com/ubuntu/pool/main/libt/libtool/libltdl7_2.2.4-0ubuntu4_i386.deb

sudo dpkg -i libltdl7_2.2.4-0ubuntu4_i386.deb

wget http://fr.archive.ubuntu.com/ubuntu/pool/main/libt/libtool/libltdl3_1.5.26-1ubuntu1_i386.deb

sudo dpkg -i libltdl3_1.5.26-1ubuntu1_i386.deb


Voilà!
