//[2] => 38 PING
//[3] => LO-DC2012 HOSTNAME

foreach ($file_txt as $line) {
$valori = explode(“;”, $line);
$Download[$i] = array(“y” => $valori[1],”label” => $valori[0] );
$Upload[$i] = array(“y” => $valori[4],”label” => $valori[0] );
$Ping[$i] = array(“y” => $valori[2],”label” => $valori[0] );
$i++;
