Download Status with PHP and JavaScript

Not really possible cross-browser, but have a look into http://markmail.org/message/kmrpk7w3h56tidxs#query:jquery%20ajax%20download%20progress+page:1+mid:kmrpk7w3h56tidxs+state:results for a pretty close effort. IE (as usual) is the main culprit for not playing ball.

You can do it with two seperate php files, first file for downloading process. Like as:

$strtTime=time();
$download_rate=120;   //downloading rate  
    $fp = fopen($real, "r");
      flush();// Flush headers
    while (!feof($fp)) {   
     $downloaded=round($download_rate * 1024);
        echo fread($fp,$downloaded );
        ob_flush();
       flush(); 
        if (connection_aborted ()) {

     // unlink("yourtempFile.txt" ;
            exit;
        }

     $totalDw +=$downloaded;
     // file_put_contents("yourtempFile.txt", "downloaded: $totalDw ; StartTime:$strtTime");
          sleep(1);
    }
    fclose($fp);
   // unlink("yourtempFile.txt") ;

Second file would be used for reading yourtempFile.txt by Ajax continusly. Using Sessions and Cookies wouldn't be used because of starting print.
