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>'; } ?> > > Christian > > "Larry Brown" <larry.brown@dimensionnetworks.com> wrote in message > > news:CBECIONKKLMDDCIKHALJCEEIKDAA.larry.brown@dimensionnetworks.com... > > I don't know of a function, but you could possibly read the directory > where > > the SID files are stored.
