Introduction

Want to get the latest major version of PHP on your dedicated server ? This article will help you to install the new PHP in a few commands and thus boost your sites and CMS running PHP (Performance up to 3 times higher under Wordpress 4.3.1!).

What is PHP ?

PHP is a computer programming language that permit to make a dynamic website, PHP is one of the most used languages to develop a website. PHP 7 is the final version of the older version of PHP.

Installation

Careful, currently the official Debian 8 deposits do not have the new version of PHP, the package will only be available from Debian 9. However, it is still possible to benefit from PHP on your server under Debian 8. This article is aimed primarily at users with a dedicated server without Plesk installation.

Adding the Dotdeb Deposit

As previously stated, the new version of PHP is not yet available in official Debian repositories, so we will need to set up Dotdeb deposits, an unofficial repository for Debian containing, among other things, version 7 of PHP


  • Adding Deposit :
# On ajoute le nouveau dépôts à notre liste
echo "deb http://packages.dotdeb.org jessie all" > /etc/apt/sources.list.d/dotdeb.list
# On ajoute la clé GPG d'identification du dépôts
wget -O- https://www.dotdeb.org/dotdeb.gpg | apt-key add -
  • Update deposites :
apt-get update

Removing PHP 5.x

  • Retrieve the list of installed php 5 modules.

It may be useful to keep the list of php 5 packages currently installed on your server for reinstallation in PHP 7. 

dpkg --list | grep php | awk '/^ii/{ print $2}'
  • If PHP5 is already installed and you do not want to make both versions (choice presented in this article) cohabit with your Apache2 installation
# Removing all PHP5 packages and dependencies
apt-get autoremove --purge php5*

Installing PHP 7

# Installation of  PHP 7 as well as some dependencies and main modules for Apache
apt-get install php7.0 libapache2-mod-php7.0 php7.0-fpm php7.0-mysql php7.0-curl php7.0-json php7.0-gd php7.0-intl php7.0-mbstring php7.0-xml php7.0-zip
Note: 7.0-[module]

Test PHP 7

TYou have the possibility to test your new version of PHP using the function phpinfo() to display various information about your web server. To do this, create a new file info.php in the tree view of your website and having for content : 

<?php
  phpinfo();
?>

Access will be conducted at serveur /info.php

Conclusion

Under Apache the PHP 7 module is activated automatically, you now benefit from a functional installation ! Attention, if you chose to delete the old installation PHP 5 you probably noticed that PHPMyAdmin was part of the packages deleted during the operation. Indeed PMA requires a functional installation of PHP 5.x in order to be executed If you want to keep PHPMyAdmin, you will need to have both versions of PHP on your server
