Hello.

When a page is saved, it is send through a number of functions which are 
listed in the $EditFunctions variable.

You can insert your own functions in the $EditFunctions array, before and 
after the 'PostPage' value. You may need array_search(), array_slice(), 
array_splice(), array_unshift() or other core PHP functions
( http://php.net/manual/en/ref.array.php ).

These functions look like :
 function MyFunction($pagename, &$page, &$new) { /*my code*/ }

where $page is an array containing the existing (old) page, $new is the new 
content that the user has posted, and $new['text'] is the page text without 
any additional metadata. Your functions can also modify the arrays. They 
return nothing.

Thanks,
Petko
