Well if things are done correctly, the only thing that may become an issue is max_execution_time. The basic logic for sending a file with php is: // authenticate the user (if they can download this or not) // send headers, like content-length, content-type, // content-disposition etc. // set_timelimit(0); if the user is on a slow connection.. // ignore_user_abort(false); see below // use either readfile() or fpassthru() // if this line is executed the user has mantained a connection so // far, so you are pretty much sure they recieved, or it is a PEBCK // issue, you can do things like add a successful counter or // something here.
