Hey,
Okay i know that the PHP.ini has the setting to automatically include file(s) at the begining and end of all files

but how could i do this to certain accounts i host i want to so i can force ads/ad a banner to top of all pages (like i have on most of my sites)

but i dont want to cause PHP/display errors... any ideas?

sounds like a job for mod_layout
http://tangent.org/362/mod_layout.html

mod_layout is an Apache module that provides both a Footer and Header directive to automagically include output from other URIs at the beginning and ending of a Web page. It can be used to wrap documents for a standard look and feel for a site (or to insert banners on any given document in a site). Currently known to support mod_perl, PHP and Apache JServ. Should support just about any type of handler.

Or by specifying

php_value auto_prepend_file /var/www/site/prepend.html
php_value auto_append_file /var/www/site/append.html

In the virtual host definition

Talked to my host, aparently i need to be VPS to be able to do this :-(
