Ubuntu 12.04 (Precise Pangolin) with latest PHP

如何让ubuntu 12.04 apt-get install 最新版本的PHP?

1. Install the signing key for the PPA (which also adds the sources to apt):

add-apt-repository ppa:ondrej/php5

If the above command is not available, install it using:

apt-get install python-software-properties

2. Now update the package database and then upgrade the system. As part of upgrading, PHP 5.4 will be installed automatically:

apt-get update
apt-get upgrade
apt-get dist-upgrade

# php -v  // will show you the latest php version.
