PHP is an open source scripting language used for server-side web development. It originated from Perl scripts created by Rasmus Lerdorf in 1994 and has since evolved with contributions from the PHP Group. PHP powers over 20 million websites by enabling dynamic content and interacting with databases and other systems through a web server. Popular uses of PHP include powering websites, blogs, forums, wikis, and content management systems.
