We can install PHP 5 and the Apache PHP 5 module as follows:

apt-get -y install php5 libapache2-mod-php5

apt-get install php5-mysqlnd

UUID:
# blkid

/dev/vdb1: UUID="f6c741e8-6595-4952-9c62-0c82b6155700" TYPE="ext4" PARTUUID="8811bc88-b63c-4a74-8fd5-3fa33f9d2454"

# nano /etc/fstab
add a line like the following
UUID=f6c741e8-6595-4952-9c62-0c82b6155700 /var/www        ext4    errors=remount-ro 0       1
