Let's talk about how to install PHP and related tools

When learning web development or operating a website, PHP is the most widely used scripting language. If you want to set up a PHP development environment on your computer, you must install PHP. This article will introduce how to install PHP and related tools.

1. Download PHP:

First enter the official website of PHP (https://www.php.net/downloads.php) and select the PHP version you want. On the download page, there are different versions of Windows and Linux operating systems available for download, and the corresponding version and file size information will also be provided on the download page.

2. Install PHP:

Installing PHP on Windows is relatively simple. You only need to download the corresponding PHP installation program and execute it. There are many different methods of installation on Linux, two will be introduced here:

1. Apache and PHP module package:
   This method installs PHP as an Apache module. Under Linux, Apache is the most commonly used HTTP server. After you need to download and install Apache, enter the following instructions in the command line terminal:
   sudo apt-get update
   sudo apt-get install apache2
   Then install the PHP module:
   sudo apt-get install libapache2 -mod-php7.4
   This command will install a PHP version matching Apache. After installation, you need to restart the Apache server:
   sudo service apache2 restart
   After that, you can create a simple PHP file test.php in the /var/www/html folder, and then enter it in the web browser "http: //localhost/test.php" to access it.
2. CGI and FastCGI methods:
   This method is to install PHP as a stand-alone program without installing Apache. After enabling CGI (Common Gateway Interface) and FastCGI (a replacement for CGI), run the following command in the command line terminal:
   sudo apt-get update
   sudo apt-get install php7.4-cgi
   After the installation is complete, you need to add the following content to the configuration file:
   sudo nano /etc/nginx/sites-enabled/default
   Add the following content to the file:
   location ~ .php$ {
   try_files $uri =404;
   fastcgi_pass unix:/var/run/php/php7.4-fpm.sock;
   fastcgi_index index.php;
   fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
   include fastcgi_params;
   }
   After the configuration is completed, you need to restart the server:
   sudo service nginx restart

3. Install PHP related tools:

Installation completed After PHP, you can also install some related tools to facilitate PHP development. The following are some commonly used tools and software:

1. Composer
   Composer is a PHP package manager through which you can easily download and install PHP libraries, frameworks and toolkits. To use Composer, you first need to download and install Composer:
   curl -sS https://getcomposer.org/installer | php
   sudo mv composer.phar /usr/local/bin/composer
   After that, you can Execute composer in a command line terminal to verify that the installation was successful.
2. PHPUnit
   PHPUnit is a popular PHP testing framework that is very useful in PHP development. You can use the following command to install PHPUnit:
   composer require --dev phpunit/phpunit ^8.0

4. Summary:

Installing PHP is a must-master in web development skill. Through the method introduced in this article, you can successfully install PHP and configure related tools whether on Windows or Linux operating systems. After mastering these skills, developers will be able to carry out PHP-related work more conveniently, improve development efficiency, and reduce error rates.
