How to Install PHP in Linux
If you’re a developer working on a Linux operating system, installing PHP is a crucial step to get your environment set up for web development. PHP is a popular server-side programming language that is commonly used for building dynamic web applications. In this guide, we will walk you through the steps to install PHP on your Linux system.
1. Update Your Package Repository
Before installing PHP, it is important to ensure that your package repository is up to date. You can do this by running the following command in your terminal:
sudo apt-get update
2. Install PHP
Once your package repository is up to date, you can proceed to install PHP. Use the following command to install PHP:
sudo apt-get install php
This command will install the latest version of PHP available in your package repository. After the installation is complete, you can verify the installation by checking the PHP version:
php -v
3. Install PHP Extensions
Depending on your project requirements, you may need to install additional PHP extensions. You can search for available PHP extensions by running the following command:
apt-cache search php-
To install a specific PHP extension, use the following command:
sudo apt-get install php-extension-name
Replace extension-name with the name of the extension you want to install. After installing the extensions, you may need to restart your web server for the changes to take effect:
sudo systemctl restart apache2
4. Test Your PHP Installation
To test your PHP installation, you can create a simple PHP file and run it in your web browser. Create a new file named info.php in your web server’s root directory with the following content:
<?php phpinfo(); ?>
Access this file in your web browser by navigating to http://localhost/info.php. You should see a page displaying detailed information about your PHP installation.
Conclusion
By following these steps, you can easily install PHP on your Linux system and start developing web applications. Remember to keep your PHP installation up to date with the latest security patches and updates to ensure a secure development environment.
