Answer 2

First, remove LAMP from your Ubuntu. Then, use the following:

sudo apt-get update
sudo apt-get install apache2 php5 mysql-server mysql-client php5-mysql //install php 5.3
sudo apt-get install python-software-properties
sudo add-apt-repository ppa:ondrej/php5
sudo apt-get remove php5 //remove php 5.3
sudo apt-get update
sudo apt-get install php5 //install php 5.4

Answer 3

First you must install PHP 5.4 (if you have not already done so):

sudo apt-get install php5-fpm php5-mysql

And then:

Apache:

sudo a2dismod php7.0 ; sudo a2enmod php5.4 ; sudo service apache2 restart

CLI:

sudo update-alternatives --set php /usr/bin/php5.4
