Through this, a framework was supplied to the user. With the help of which users may create basic dynamic web apps such as guestbooks.



In June 1995, Rasmus released the source code for PHP tools, now developers could improve on dynamic web applications developed with the aid of this code as well as fix problems in the code. In a manner, the developer was allowed that he may fit it anywhere he wants. After this numerous improvements were done in PHP. Many programming languages ​​were also developed.



After this, many improvements were done in PHP, several programming languages ​​were also developed. PHP 3.0 was published in 1997 which was the first version of PHP.

How does PHP work?

The interface means that it converts the request provided to the server into machine language.
