Created in 1994, PHP was originally a simple set of Common Gateway Interface (CGI) binaries written in the C programming language. Rasmus Lerdorf designed PHP to track visits to his online resume. In June of 1995, Rasmus released the source code, used to create his tools, to the public. Soon after Rasmus released the source code to the public, developers were allowed to utilize the code as they desired. Furthermore, developers encouraged others to fix bugs and improve upon PHP.
In September of 1995, Rasmus expanded upon PHP and even dropped the PHP name for a short period of time. He began calling it FI (Forms Interpreter). In April of 1996, Rasmus introduced PHP/FI. That is when PHP/FI really started to become a programming language. In June of 1996, PHP/FI was given version 2.0 status.
In 1997 and 1998, PHP/FI already had more than a few thousand users around the world. In fact, a Netcraft survey, in 1998, reported more than 60,000 Websites were using PHP. At the time, this number was only 1% of total Websites online.
