Programming Languages Web Development Server-side Scripting

Rasmus Lerdorf (born 1968) is a Danish-Canadian programmer who created PHP. What started as simple tools for his personal homepage grew into the most widely used server-side scripting language on the web.

Creating PHP

In 1994, Lerdorf wrote some C programs to track visits to his online resume. He released these “Personal Home Page Tools” publicly. Other developers contributed, and PHP evolved from a simple toolset into a full programming language.

Pragmatic Philosophy

Lerdorf has described PHP’s development as organic and practical rather than designed:

This pragmatic approach—solving immediate problems without grand architectural plans—characterized PHP’s evolution.

Continued Involvement

Lerdorf worked at Yahoo and later Etsy, contributing to PHP’s optimization and real-world deployment. He remains an advocate for practical, pragmatic programming.
