== Early life and education ==

'''Rasmus Lerdorf''' (born 22 November 1968) is a Greenlandic-Danish [[computer programmer]] best known as the creator of the [[PHP]] scripting language. He was born in [[Qeqertarsuaq]], [[Greenland]], and moved to [[Denmark]] as a child. Lerdorf studied at the [[University of Waterloo]] in Canada, where he earned a bachelor's degree in [[systems design engineering]].

== Career ==

After university, Lerdorf worked for several companies including the [[Internet service provider]] [[IBM Canada]] and the software company [[Nexus Media]]. In 1995, he began developing a set of [[Common Gateway Interface]] tools for his personal web page, which he initially called "Personal Home Page Tools". Over time, he expanded the project into a full scripting language, releasing it publicly as [[PHP/FI]] (Personal Home Page / Forms Interpreter). This early version attracted interest from other developers, most notably [[Zeev Suraski]] and [[Andi Gutmans]] of the [[Technion – Israel Institute of Technology]], who later rewrote the parser and created [[PHP 3]] and [[PHP 4]].

Lerdorf continued to contribute to the PHP project and served as a core developer. He also worked on other open‑source projects, including the [[Apache HTTP Server]], and co‑authored the book ''[[PHP Pocket Reference]]''. In 2002, he joined [[Yahoo!]] as a [[software engineer]], and later held positions at [[WePay]] and [[Etsy]]. As of 2025, he is a principal engineer at [[JetBrains]].

== PHP and legacy ==

Lerdorf's design of PHP emphasised simplicity and ease of use for web development. The language has become one of the most widely used server‑side scripting languages, powering a large portion of the [[World Wide Web]]. While Lerdorf did not intend to create a general‑purpose programming language, his work laid the foundation for the modern PHP ecosystem, including frameworks such as [[Laravel]] and [[Symfony]].

In addition to PHP, Lerdorf has contributed to the [[PostgreSQL]] and [[SQLite]] projects, and has spoken at numerous technology conferences, advocating for pragmatic programming and performance optimisation.
