When was php invented?

PHP (foreign name: PHP: Hypertext Preprocessor, Chinese name: "Hypertext Preprocessor") is a general open source scripting language. The syntax absorbs the characteristics of C language, Java and Perl, which is easy to learn and widely used. It is mainly suitable for the field of Web development. PHP's unique syntax mixes C, Java, Perl, and PHP's own syntax. It can execute dynamic web pages faster than CGI or Perl.

PHP was originally created by Rasmus Lerdorf in 1994. It was just a simple program written in Perl language to maintain personal web pages and count visits to his own website. By. 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 1995, the first version began to be released as Personal Home Page Tools (PHP Tools). Lerdorf wrote some documents introducing this program and released PHP1.0! In this early version, simple functions such as guest book and visitor counter were provided. In the future, more and more websites use PHP, and there is a strong need to add some features, such as loop statements, array variables, etc.

On June 8, 1995, Rasmus Lerdorf released PHP/FI to the public, 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.
