It depends on your definition of 'active.' If you wanted to see if the
specific session you are looking at has been used in the past half hour,
that is possible. Following is a script I've used to help debug sessions
sometimes. While it's not what you're asking for, it may help you figure
out how to do it. It may need tweaking to run on your server.
<? // sessioninfo.php
$path = ini_get('session.save_path');
if (isset($_GET['empty']))
{
if (isset($_COOKIE['PHPSESSID']))
setcookie('PHPSESSID', '');
header('Location: sessioninfo.php');
}
if (count($_GET) == 0)
{
echo "<br>Path: $path<br>";
$dir = dir($path);
while ($file = $dir->read())
{
$file_arr[$file]['time'] = filectime($path . '/' . $file);
$file_arr[$file]['size'] = filesize($path . '/' . $file);
}
$dir->close();
asort($file_arr);
echo '<table
border=1><tr><th>Time</th><th>Size</th><th>SessionID</th></tr>';
foreach($file_arr as $fname => $data)
{
if ($fname == '.' || $fname == '..')
continue;
$ftime = date('Y-m-d G:i', $data['time']);
$sessid = substr($fname, 5);
echo "<tr><td>$ftime</td><td>{$data['size']}</td><td><a
href=\"?sessionid=$sessid\">$fname</a></td></tr>";
}
echo '</table>';
} else if (isset($_GET['sessionid'])) {
setcookie('PHPSESSID', $_GET['sessionid']);
header('Location: sessioninfo.php?show=true');
exit();
} else {
session_start();
echo '<pre>';
print_r($_SESSION);
print_r($_GET);
echo '</pre>';
}
