PHP
PHP was originally an acronym for Personal Home Pages, but is now a recursive acronym forPHP: Hypertext Preprocessor.
PHP was at first created as a simple scripting platform called "Personal Home Page". Nowadays PHP (the short for Hypertext Preprocessor) is an alternative of Microsoft's Active Server Pages (ASP) technology.
PHP is a widely-used general-purpose scripting language and interpreter that is freely available.
PHP is an open source server-side language which is used for creating dynamic web pages. It can be embedded into HTML.
How php works:
When a user is viewing .php extension webpage (such as index.php), the PHP process begins.
The php statements within the page is requested by the web server and then its directed to the PHP interpreter.
At this point the PHP interpreter does all the processing of the PHP page by commuunicating with file systems, databases, and email servers if it is necessary.
Finally, once all the processes is completed the processed PHP statements is then sent back to the web server and is then delivered to the browser as nice readable PHP web page.

Managing Databases

Although all the database administrative options can be done through PHP scripts, I strongly suggest installing a copy of PHPMyAdmin on your server. It is an excellent free set of scripts that will provide you with an administrative interface for your MySQL database(s). You can add, remove, edit, backup and view your databases using this and it is especially useful when troubleshooting your databases.
