Fifteen years ago today, on the 8th of June, 1995, Rasmus Lerdorf launched PHP with a post to the comp.infosystems.www.authoring.cgi Usenet news group. He announced version 1.0 of his "Personal Home Page Tools", software that was originally intended for managing job applications on a web site. As Lerdorf made the tools available as open source code (originally under the GPL, since version 4.0 under the PHP Licence) his PHP software, written in C, was bound to find a wide audience.
