What is PHP?

A widely-used server-side scripting language designed for web development that powers over 75% of websites including WordPress.

PHP (PHP: Hypertext Preprocessor) runs on the server, generating dynamic HTML pages. It integrates seamlessly with databases (MySQL, PostgreSQL), web servers (Apache, Nginx via PHP-FPM), and supports object-oriented and procedural programming.

Modern PHP (8.x) includes type declarations, named arguments, fibers, enums, and match expressions. Popular frameworks include Laravel, Symfony, and WordPress. PHP excels at web applications, CMSs, and e-commerce platforms.
