you can do a force type of script... so make a script called
myscript.php
rename it
myscript
add to .htaccess
<Files /myscript>
ForceType php-script #if phpcgi
ForceType application/x-httpd-php #if mod_php
</Files>
Then depending on phpcgi or mod_php, you can read in the request_uri (mod_php) or create a rewrite rule to change anything after myscript to ?info and then read in the request_query information (i dont remember the syntax for that rewrite tho)
