Prova Così con txt:
Codice PHP:
<?php
$timer = 2;
$filename = "utenti.txt";
if (!$datei) $datei = dirname(__FILE__)."/$filename";
$time = @time();
$ip = $REMOTE_ADDR;
$string = "$ip|$time\n";
$a = fopen("$filename", "a+");
fputs($a, $string);
fclose($a);
$timeout = time()-(60*$timer);
$all = "";
$i = 0;
$datei = file($filename);
for ($num = 0; $num < count($datei); $num++) {
$pieces = explode("|",$datei[$num]);
if ($pieces[1] > $timeout) {
$all .= $pieces[0];
$all .= ",";
}
$i++;
}
$all = substr($all,0,strlen($all)-1);
$arraypieces = explode(",",$all);
$useronline = count(array_flip(array_flip($arraypieces)));
if ($useronline == 0) {
$useronline = 1;
}
// Löschen
$dell = "";
for ($numm = 0; $numm < count($datei); $numm++) {
$tiles = explode("|",$datei[$numm]);
if ($tiles[1] > $timeout) {
$dell .= "$tiles[0]|$tiles[1]";
}
}
if (!$datei) $datei = dirname(__FILE__)."/$filename";
$time = @time();
$ip = $REMOTE_ADDR;
$string = "$dell";
$a = fopen("$filename", "w+");
fputs($a, $string);
fclose($a);
?>
