How do I upgrade from PHP 5.3 to PHP 5.4.6 in Ubuntu?
Solution 1:
Installing PHP 5.4.* on Ubuntu 12.04
Simply add the PPA repository:
sudo add-apt-repository ppa:ondrej/php5-oldstable
And install it:
sudo apt-get update
sudo apt-get install php5
You may need to install add-apt-repository on Ubuntu 12.04. To do so, run the command:
sudo apt-get install python-software-properties
Other New Versions
For PHP 5.5 (currently 5.5.30) add the PPA repository instead:
sudo add-apt-repository ppa:ondrej/php5
For PHP 5.6 (currently 5.6.14) add the PPA repository instead:
sudo add-apt-repository ppa:ondrej/php5-5.6

WARNING: - this will also auto-upgrade Apache (now 2.4) which has additional consequences, i.e. there are big config changes between Apache 2.2. and 2.4 that will prevent the Apache service from running afterwards!
