Answer 1

You can use the Ondrej oldstable PPA to install php 5.4. First you need to remove the existing php.

sudo apt-get remove --purge `dpkg -l | grep php | grep -w 5.5 | awk '{print $2}' | xargs`

sudo apt-get install python-software-properties

sudo add-apt-repository ppa:ondrej/php5-oldstable

sudo apt-get update

sudo apt-get install -y php5
