What does the first p of php mean?

Here we are going to learn about the development history of PHP!

PHP, originally referred to as Personal Home Page, is some CGI tool assemblies developed by Lasmus Ledorf in C language to replace the original Perl programs in order to maintain personal web pages. Initially, these tool programs were used to display Lasmus Ledorf's resume and to count web traffic.

He integrates these programs with some form interpreters, called PHP/FI.

PHP/FI can connect to the database to produce a simple dynamic web program. Rasmus Ledorf publicly released PHP/FI on June 8, 1995, hoping to speed up program development and find errors through the community. This release, named PHP 2, already has some prototypes of today's PHP, such as Perl-like variable naming, form handling, and the ability to embed execution in HTML. The program syntax is also similar to Perl, with more restrictions, but simpler and more flexible.

In 1997, two Israeli programmers, Zeev Suraski and Andi Gutmans, who worked for Technion IIT, rewrote PHP's parser, which became the foundation of PHP 3, and PHP was renamed PHP: Hypertext Preprocessor.

After several months of testing, the development team released PHP/FI 2 in November 1997, followed by open testing of PHP 3, and finally officially released PHP 3 in June 1998.

Zeev Suraski and Andi Gutmans began to rewrite the core of PHP after the release of PHP 3, a parser called Zend Engine, which was released in 1999. They also set up Zend Technologies in Ramat Gan in Israel to manage the development of PHP.

On May 22, 2000, PHP 4 based on Zend Engine 1.0 was officially released, and on July 13, 2004, PHP 5 was released with the second generation of Zend Engine [9]. PHP 5 includes many new features, such as enhanced object-oriented functionality, the introduction of PDO (PHP Data Objects, an extension library to access databases), and many performance enhancements. Currently, PHP 4 will not be updated to encourage users to move to PHP 5.

In 2008, PHP 5 became the only stable version of PHP under maintenance.

The first version of PHP 7 was developed on December 3, 2015 and includes a number of performance improvements as well as some new features, most notably return value type declarations and scalar type declarations (available for parameters and return values).
