Hi,
Unfortunately not. If you have a generous host they can put the following in your vhost config
ScriptAlias /php/ "/usr/local/bin/"
AddType application/x-httpd-php .php
AddHandler "/php/php"
But your host is probably security-concious which is why they have configured php so you can only activate a script by having the hash-bang at the top of every page. It can also hault attacks on the server through holes in php.
