echo "Pinging servers. Stand by...";
$dator[0] = "www.sunet.se";
$dator[1] = "www.stenerlov.com";
$dator[2] = "www.jonne.nu";
$dator[3] = "intranet.windh.net";
$dator[4] = "www.errormess.com";
echo "<table>";
for ($counter=1; $counter < 5; $counter++) {
exec("ping -c 2 $dator[$counter]", $data, $value);
if ($value == 0) {
echo "<tr>";
echo ("<td><IMG SRC=\"on.jpg\" WIDTH=\"10\" HEIGHT=\"10\" BORDER=\"0\"> $dator[$counter]</td>");
echo "</tr>";
} else {
echo "<tr>";
echo ("<td><IMG SRC=\"off.jpg\" WIDTH=\"10\" HEIGHT=\"10\" BORDER=\"0\"> $dator[$counter]</td>");
echo "</tr>";

}
echo "</table>";
