PHP
From DmWiki
PHP is a Server Side Scripting langauge. Created by Rasmus Lerdorf, and was originally intended for website widgets. PHP has functionality with databasing, user content, email, and many other dynamic functions. Infact, the page you're using now is actually scripted in PHP.
PHP is derived from a Python and C like syntax. It can easly be called inside any html, as long as you have php on your server, and you have .php file extension. By editing the .htaccess file you can make PHP run on a .html file.
[edit]
Example
<html>
<head> <title>A php Page</title> </head> <body> <?php $second = "
And to you too!"; echo'Hello World!'; echo($second); ?> </body
</html>
That will parse through the web server, and you won't see the php code.
But you'll get: Hello World! And to you too!
