PHP was created by Rasmus Lerdorf in 1994. It started as a simple program written in Perl language by Rasmus Lerdorf to maintain a personal web page. These tools are used to display Rasmus Lerdorf's resume and count web traffic. Later it was rewritten in C language, including access to the database. He integrated these programs with some form interpreters and called them PHP/FI. PHP/FI can be connected to the database to generate simple dynamic web programs.

In this version, simple functions such as guest book and visitor counter are provided. In the future, more and more websites are using PHP, and there are strong requests to add some features. For example, loop statements, array variables, etc.; after new members joined the development team, Rasmus Lerdorf released PHP/FI to the public on June 8, 1995, hoping to speed up program development and find errors through the community. This released version, named PHP 2, already has some prototypes of PHP, such as Perl-like variable naming, form processing capabilities, and the ability to embed execution in HTML. The program syntax is also similar to Perl, with more restrictions, but it is simpler and more flexible. PHP/FI added support for MySQL, and has since established PHP's position in dynamic web development. By the end of 1996, there were 15,000 websites using PHP/FI.

In 1997, two Israeli programmers working at Technion IIT: Zeev Suraski and Andi Gutmans, rewrote the PHP parser and became the basis of PHP 3. At this time, PHP was also renamed PHP: Hypertext Preprocessor. After several months of testing, the development team released PHP/FI 2 in November 1997. Then the open testing of PHP 3 began, and finally PHP 3 was officially released in June 1998. Zeev Suraski and Andi Gutmans began to rewrite the core of PHP after the release of PHP 3. The profiler released in 1999 was called Zend Engine. They also established Zend Technologies in Ramat Gan, Israel, to manage PHP development.
