Hypertext Preprocessor, or PHP, is a server-side language primarily used for creating web servers. PHP is a platform-independent language that works effectively with HTML and syncs with nearly all relational and non-relational databases.
PHP can be an excellent choice for web application development. Many industry-leading sites, including Facebook, WordPress, Shopify, and Wikipedia, are built on PHP infrastructures. PHP is also open source, which allows users to access and build upon numerous frameworks and collaborate with other users.
