Introduction

As a major update to the PHP language, PHP7 offers significant improvements in performance and security. This article will guide you step-by-step through installing and configuring PHP7 in your development environment to boost your development efficiency.

Installing PHP7

Checking Prerequisites

Before installing PHP7, check if PHP is already installed on your system and verify its version to avoid conflicts with old versions.

php -v

If an older PHP version is detected, it is recommended to uninstall it first to ensure a smooth installation process.

Downloading PHP7

Download the PHP7 source package from the official PHP website or a trusted mirror.

wget http://php.net/get/php-7.0.0.tar.gz/from/this/mirror

This command downloads the PHP7 compressed source file to the current directory for subsequent extraction and compilation.

Extracting and Compiling

Extract the source package and enter the directory to prepare for compilation and installation.

tar xzf php-7.0.0.tar.gz
cd php-7.0.0

Run the configuration script and compile PHP7 with the following commands:

./configure --prefix=/usr/local/php7
make
make install

After these steps, PHP7 will be installed in the specified directory.

Configuring PHP7

Modifying Configuration File

Copy the development php.ini template file and adjust configuration parameters as needed, such as memory limits and error reporting.

sudo cp php.ini-development /usr/local/php7/lib/php.ini
sudo vi /usr/local/php7/lib/php.ini

Configuring the Web Server

If you want to use PHP7 with a web server, update the web server configuration file to point to the new PHP7 interpreter path.

Restarting the Web Server

Restart the web server after making changes to apply the new settings.

Using PHP7

With PHP7 installed and configured, you can start writing and running PHP code.

Example of running a PHP script via command line:

php /path/to/script.php

You can also run PHP scripts through a web server and access them via a browser for dynamic web pages.
