Its Official name is Hypertext preprosessor, and it is server side scripting language. When your web browser access a url. It is making a request to web server. When you request a PHP page, something like http://www.companyname.com/index.php, the web server wakes up the php parse engine and provide result back to the browswer. This output is passed back to the Web server as part of the HTML code in the document, which in turn is passed on to your browser, which displays it to you.
In 1994, an incredibly forward-thinking man named Rasmus Lerdorf developed a set of tools that used a parsing engine to interpret a few macros here and there.He eventually combined these tools with a form interpretation (FI) package he had written, added some database support, and released what was known as PHP/FI. By 1997, more than 50,000 Web sites were using PHP/FI to accomplish different tasks—connecting to a database, displaying dynamic content, and so on. After some time, the final release of PHP 3.0 occurred in June of 1998 and so on development is in progress with many new verions as PHP 4.0, PHP 5.0 and PHP 6.0 with many new things.
