PHP is a very popular programming language, and it is very important for developers to build a suitable running environment. In this article, we will explore how to set up a PHP running environment.

1. Select the operating system

First, you need to choose an operating system that suits you for installation. PHP can run in most operating systems such as Windows, macOS, Linux, Unix, etc.

If you are a novice, Windows system will be a better choice because it is relatively simple and easy to use. But if you want a more professional building experience, Linux or Unix would be a good choice.

2. Select the Web server

The Web server is also a very important part of the entire operating environment. Currently, the most famous web servers are Apache and Nginx. Of course, there are others such as LiteSpeed ​​and Lighttpd.

If you are a novice, it is recommended to use Apache, an old web server. It has been around for many years and remains one of the most popular web servers.

3. Install PHP

When installing PHP, we'd better use the ready-made PHP running environment. This avoids reinventing the wheel.

Now, many web server software packages include a PHP environment by default. For example, if you are using Apache, you can use XAMPP or WAMP packages to automatically install and configure your PHP environment.

Of course, you can also use Linux package management tools to install PHP. The instructions may vary slightly between different Linux distributions. The following are some more general instructions:

  • Debian/Ubuntu : sudo apt-get install php7.2
  • Red Hat/Fedora : sudo dnf install php7.2
  • CentOS: sudo yum install php7.2

4. Test the PHP operating environment

After installing the PHP operating environment, we need to test it whether it can operate normally.

First, create a PHP file. This file can be named index.php and placed in the site root directory of your web server.

Next, enter the following code:

<?php phpinfo(); ?>
Copy after login

Save the file and access the PHP file via the URL in your browser. For example, if your site is on localhost, visiting http://localhost/index.php will display the PHP information page.

If the PHP environment can run normally, the page should display information about PHP version information, compiler information, and compilation parameters.

5. Debugging

If you encounter any problems, such as the PHP environment not running properly, you should give priority to using debugging tools to find the problem.

Most web servers and PHP frameworks have corresponding debugging tools, such as Xdebug and PHPStorm. These tools can help you find errors in your code more easily and provide some useful debugging features, such as breakpoints, hit counters, etc.

Summary

The above are the main steps to build a PHP running environment. While this is not a complicated process, it does require some care and patience. Hope the above content is helpful to beginners.
