PHP - determine how many bytes sent over http

Question

Is it possible in PHP to get a count of the number of bytes transmitted to the client? For example, if I\'m outputting a 10 MB file, is there a way to find out if all 10 MB

Answer 1

Take a look at the ignore_user_abort and connection_abort function.

Answer 2

Here's what I ended up doing (thanks Gumbo):

ignore_user_abort(true);

$handle = fopen($file_path, 'r');
while ( ! feof($handle)) {
    echo fread($handle, 4096);
    if (connection_aborted()) {
        $transfer_success = false;
        $bytes_transferred = ftell($handle);
        break;
    }
}
fclose($handle);
