Include a line in all scripts (#!/usr/bin/php)

hey,

I have a big problem… i have devolped a site on a server… and now that it is complete I have to install the site on other server… but the problem is that on new server I have to include this line:

#!/usr/bin/php

…Exist any way to do this auto?
