1&1 Dedicated Website Servers (formerly called managed servers)

PHP is a web scripting language used to create dynamic web pages and interactive features that greatly exceed the functionality of simple HTML files. 1&1 Linux WebHosting packages and 1&1 Website Dedicated Servers run PHP5 as default starting Q3 2010. Any files named with the extension .php will be parsed by the WebHosting server automatically when accessed via the browser. PHP pages can be created via a text editor such as WordPad, Notepad, vi, nano, etc. and must be named with the .php extension. Regular HTML tags are used to construct the page with PHP tags included wherever PHP code is needed.
