Setting Up PHP with Memcached(Installing the Memcached PHP Extension)
Setting up PHP with Memcached involves installing the Memcached daemon and the PHP extension that allows PHP applications to communicate with it. This process enhances the capability of PHP applications by enabling them to cache data in memory. This speeds up access times and reduces database load.
Below is how you can set up PHP with Memcached:
Step 1: First, you need to install the Memcached server on your system. This can be done using a package manager like apt for Debian-based systems with the following command:
sudo apt-get install memcached
Step 2: Once the Memcached server is installed, you should ensure it’s running properly. You can check its status with the following command on systems using systemd:
systemctl status memcached
Step 3: Next, install the PHP Memcached extension. For PHP environments, this can be achieved by executing the following command for PHP 7.x versions:
sudo apt-get install php-memcached
This command automatically handles the installation of necessary PHP and Memcached dependencies.
Step 4: After installation, it’s important to restart your web server to enable the PHP extension. For Apache, use the following command:
sudo systemctl restart apache2
For Nginx, use:
sudo systemctl restart nginx
Step 5: Finally, verify the installation by creating a simple PHP script that utilizes Memcached functions to ensure everything is configured correctly.
Memcached in PHP
Memcached is a versatile caching system widely adopted for enhancing the performance of web applications. It operates by storing data in memory, which significantly reduces the need to access slower backend databases. This integration is especially beneficial for dynamic websites built with PHP, a popular server-side scripting language. Understanding how to set up and utilize Memcached can greatly improve the responsiveness of your applications. In this article, you will learn about the various aspects of Memcached within PHP environments, including installation, basic usage, and practical applications.
