// make sure it s a file before doing anything!
if(is_file($file_name))
{
/*
Do any processing you d like here:
1. Increment a counter
2. Do something with the DB
3. Check user permissions
4. Anything you want!
*/
// required for IE
if(ini_get( zlib.output_compression )) { ini_set( zlib.output_compression , Off ); }
// get the file mime type using the file extension
switch(strtolower(substr(strrchr($file_name, . ),1)))
{
case pdf : $mime = application/pdf ; break;
case zip : $mime = application/zip ; break;
case jpeg :
case jpg : $mime = image/jpg ; break;
default: $mime = application/force-download ;
}

exit();
}
