PHP is a popular server-side scripting language that makes it easy to create dynamic web pages and web applications. Installing PHP on a Linux system is easy, and this article will teach you how to complete the installation process.

Preparation before installation

Before you start installing PHP, you need to make sure that you have installed and running a web server, such as Apache or Nginx, and have root user permissions. If you haven't installed a web server yet, you need to install it first.

Install PHP

1. Update software packages

Before installing PHP, we need to update the software package list through the system package manager. On most Linux systems, you can update using the following command:

sudo apt update
Copy after login

2. Install PHP

We can use the Linux package manager to install PHP. On Ubuntu systems, you can use the following command to install the default version of PHP:

sudo apt install php
Copy after login

If you need to install a specific version of PHP, you can use the following command:

sudo apt install php7.4
Copy after login

Among them, 7.4 is PHP Version number, you can change the version number according to your needs.

3. Verify PHP

When the installation is complete, we need to verify whether PHP has been successfully installed. Create an info.php file using the following command:

sudo nano /var/www/html/info.php
Copy after login

Copy and paste the following PHP code into the file:

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

Save and close the file. Then, enter the following URL into your web browser:

http://localhost/info.php
Copy after login

If you see a page with PHP information, then PHP has been successfully installed.

4. Configure PHP

By default, PHP is automatically configured, but sometimes you need to configure it yourself. For this case, you can use the following command to open the PHP.ini file:

sudo nano /etc/php/[version]/apache2/php.ini
Copy after login

Here, [version] is the PHP version you installed, and you can change it according to the actual situation. Modify necessary options in the file. When finished, save and close the file.

Summary

Through the above steps, you have successfully installed PHP on your Linux system. Now, you can start writing PHP scripts and use them to create dynamic websites and applications. If you encounter any problems, you can refer to the PHP documentation or the Linux community for help.
