How to Install PHP 7 on Ubuntu Linux 14.04 LTS

UbuntuPHPServer Side Programming

PHP is a server-side scripting language designed for web development but also used as a general-purpose programming language. Originally created by Rasmus Lerdorf in 1994, the PHP reference implementation is now produced by The PHP Group. The latest version PHP is PHP7 and it provides 2x faster performance and 50% better memory consumption than PHP version 5.6. This article explains “How to install PHP7 on Ubuntu Linux”.

Before installing PHP7, you should need to install a PPA called ondrej/php. This allows you to co-install PHP versions 5.6 and 7.0.

Configuring a PPA for co-installable PHP 5.6 + 7.0

To configure a PPA, use the following command –

$ sudo add-apt-repository ppa:ondrej/php

The sample output should be like this –

Co-installable PHP versions: PHP 5.6, PHP 7.0 and batteries included.

You can get more information about the packages at https://deb.sury.org

For PHP 5.6 use: ppa:ondrej/php5-5.6
For PHP 5.5 use: ppa:ondrej/php5
For PHP 5.4 use: ppa:ondrej/php5-oldstable

BUGS & FEATURES: This PPA now has a issue tracker: https://deb.sury.org/pages/bugreporting.html
