PHP is a popular scripting language primarily used for developing dynamic websites and applications. Thanks to its simplicity and ease of deployment, it has become one of the most widely used languages for backend development. PHP runs on the server and generates HTML, which is then sent to the user’s browser. It is known for its compatibility with most web servers and databases, such as MySQL, making it an ideal choice for building complex web systems, including content management systems, e-shops, and forums. Some of the most well-known projects built on PHP include WordPress, Joomla, and Drupal. Thanks to its large community, PHP is constantly being improved, with modern versions offering higher performance, better security, and support for object-oriented programming.
