Being able to execute php code from within the wordPress framework is fantastic, you'll be able to add your own script and customize the page easily, if you are thinking about "how to do that?" then try this plugin; runPHP.

runPHP is a wordpress plug-in that enables you to embed php code directly into your post, created by nosq.com and the latest version (2.3.1) supported for wordpress 2.2.x and has been fixes for some important SQL-injection vulnerabilities and should work with PHP4.

Key features:

• Permission to use runPHP is controlled by Roles and Capabilities
• Configure those permissions in the new runPHP Options page
• Also works in your feeds (RSS, RSS2, Atom, & RDF)
• Better integration with WordPress 2.0 administrative UI
• Internationalization support: English (default), German, and French so far
• Refactored code - friendlier function names, encapsulated in a class
• Now works on PHP4 servers as well! (see caveats, below, though)

Similiar plug-ins:

• EzStatic3 allows you to embed other HTML or PHP pages into your WordPress posts - this a little different than what runPHP does
• PhpExec does pretty much the same thing runPHP is doing, and some people report better luck getting it to work for them.
