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

PHP, originally abbreviated as Personal Home Page, is a collection of CGI tools developed in C language by Rasmus Ledolf in order to maintain his personal web page to replace the Perl program originally used. Initially these tools were used to display Rasmus Ledolf's resume and to count web traffic.

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

PHP/FI can be connected to the database to generate simple dynamic web pages. 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 had some of the prototypes of today's PHP, such as Perl-like variable naming, form processing capabilities, and the ability to embed execution into HTML. The program syntax is also similar to Perl, with more restrictions, but it is simpler and more flexible.

In 1997, two Israeli programmers working at Technion IIT: Zeev Suraski and Andi Gutmans, rewrote PHP's syntax analyzer and became the basis of PHP 3. PHP was also renamed at this time For PHP: Hypertext Preprocessor.

After several months of testing, the development team released PHP/FI 2 in November 1997, then began 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. The syntax analyzer released in 1999 was called Zend Engine. They also established Zend Technologies in Ramat Gan, Israel, to manage PHP. development.

On May 22, 2000, PHP 4 based on Zend Engine 1.0 was officially released, and PHP 5 was released on July 13, 2004. PHP 5 used the second generation 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 for accessing databases), and many performance enhancements. Currently, PHP 4 will no longer be updated to encourage users to move to PHP 5.

In 2008, PHP 5 became the only stable version of PHP being maintained.

The first version of PHP 7 was developed on December 3, 2015. It included a large number of performance improvements and also brought some new features, the most noteworthy of which are return value type declarations and scalars. Type declaration (can be used for parameters and return values).
