PHP installation on Linux

To install PHP on a Linux system, you can use the package manager specific to your distribution. Below are instructions for installing PHP on some popular Linux distributions:

Ubuntu/Debian:

1. Update the package index:
   • sudo apt update
2. Install PHP along with commonly used modules:
   • sudo apt install php libapache2-mod-php
3. After the installation is complete, restart the Apache web server:
   • sudo systemctl restart apache2
4. To test PHP, you can create a PHP file in the web server’s document root directory. For example:
   • sudo nano /var/www/html/info.php
   • Add the following content to info.php:
   • <?php phpinfo();
   • Save and close the file.
   • Then, access info.php from a web browser by entering
   • http://localhost/info.php or http://your_server_IP/info.php.

After following these steps, PHP should be successfully installed and configured on your Linux system, allowing you to develop and run PHP-based web applications.
