PHP connection_aborted () not working on page change

I am trying to serve an image by adding a MySQL row every second the image was viewed.

I serve it in 1024 bit chunks (total image size is 20KB)

The problem is that if I load the page that displays the image and then close the window or click a link that takes me to another page, the script will work and will not work die

as it should.

ignore_user_abort(false);
$file = 'a.jpg';
header('Content-Type: image/jpeg');
header('Expires: 0');
header('Cache-Control: must-revalidate, post-check=0, pre-check=0');
header('Content-Length: ' . filesize($file));
ob_clean();
flush();

$conn = mysql_connect("localhost","user","pass");
mysql_select_db("mydb",$conn);

$fp=fopen($file,"rb");
$i=0;

while (!feof($fp)) {

    print(fread($fp,1024));
    sleep(1);
    mysql_query("INSERT INTO table (VIEWTIME) VALUES ('$i')");
    $i++;
    flush();
    ob_flush();
    if (connection_aborted()) {
        die();
    }
}

      

        
        
        
      

    

I am trying to find only a "server side" solution as I have some technical limitations that prevent me from using any JS or any client side languages.
