non dovevo mandare tutto.... in rosso è la parte che ho aggiunto come counter

case "doupload":
include "config.php";
$file_nam = "foto/count.txt";
// se il file non esiste lo creo
if(!is_file($file_nam)){
$fp1 = fopen($file_nam,"w");
$newvar = "total=0";
fwrite($fp1,$newvar,1024);
fclose($fp1);
setcookie ("counter","sephiroth counter",0,""); // Aggiungo il cookie (di sessione)
} else {
// estraggo i dati del file
$fcontents = file ('foto/count.txt');
while (list ($line_num, $line) = each ($fcontents)) {
$nome = explode("=",$line);
}

// se il cookie esiste già
if(isset($_COOKIE['counter'])){
$newvar = "$nome[0]=$nome[1]";
} else {
// se il cookie non esiste
$nome[1]++;
$newvar = "$nome[0]=$nome[1]";
$fp = fopen($file_nam,"w"); // apro il file in scrittura
fwrite($fp,$newvar); // scrivo sul file di testo
fclose($fp); // chiudo il file
setcookie ("counter","sephiroth counter",0,""); // Aggiungo il cookie (di sessione)
}
