However, below is a basic introduction to understanding and writing your own PHP to generate your web-page. This Wiki article cannot teach you PHP because it includes a very large number of functions, nor can I tell you if your web server supports PHP, but the examples below give a brief hint of how PHP could be used and should help you to get started. | However, below is a basic introduction to understanding and writing your own PHP to generate your web-page.

This makes for a more secure script, because it only runs on the web site server. For instance if information is read from a database or in another way involves a password of some kind, all that code can be hidden, the end-user then has no way to modify the script to get information that should not be seen by others. A disadvantage is that it can be more complicated to update information on a page, requiring the whole page to be regenerated. (Consequently, a mix of scripts may be used with updating by AJAX or JSON, added to the PHP that generates the basic page. That is beyond the scope of this article). | ||
