What is PHP?
PHP (Hypertext Preprocessor) is a widely used, open-source server-side scripting language designed specifically for web development. It is embedded within HTML and executed on the server to generate dynamic web pages, powering approximately 77% of all websites with a known server-side language, including WordPress, Facebook, and Wikipedia.
How Does Php Work?
PHP code is processed by the web server before the resulting HTML is sent to the client's browser, meaning users never see the PHP source code. The language offers extensive built-in support for database interaction (especially MySQL and PostgreSQL), file handling, session management, and string manipulation. Modern PHP (versions 8.0+) includes features like just-in-time compilation, named arguments, attributes, union types, and fibers for improved performance and developer productivity.
PHP is the most universally supported server-side language in web hosting. Virtually every shared, VPS, and dedicated hosting plan supports PHP, and it is a core component of the LAMP stack. Hosting providers typically offer multiple PHP version options and the ability to configure PHP settings like memory limits, execution time, and extensions through php.ini or control panel interfaces. For optimal performance and security, it is important to run the latest stable PHP version and keep all PHP-based applications like WordPress and its plugins up to date.
