Here's a little script that gets the session ID and the creation and modified timestamps, plus prints out the contents of the session array.
It relies on knowing the path to the temporary folder that contains the session file (variable $sessfile).  On my server, the path shown works, but you may have to modify.

One significant issue:  when I run this on my local Windows XAMPP setup it gets different timestamps for creation and modified, but on my live server running Linux/Apache, I get the same time stamp for created and modified.  Did some googling and it appears this is just the way Linux file system works -- creation time is the time the file was last changed.  So I'm stumped about how to get the true session creation time in a Linux environment.
<?php  session_start();
$_SESSION['testvalue']="test string 1";
$_SESSION['testvalue2']="test string 2";
?>
<html>
<head>
<title>Checking PHP session info</title>
</head>
<body>
<?php  
$sid=session_id();
$sessfile="/tmp/sess_".$sid;
echo $msg. "<BR>"; 
echo "Session ID is: ". $sid. "<BR>"; 
echo "Session was created at: ".date("m/d/y H:i:s T", filectime($sessfile)). "<BR>";
echo "Session was modified at: ".date("m/d/y H:i:s T", filemtime($sessfile)). "<BR>";
foreach ($_SESSION as $i => $value) {
echo "Value: $i : $value <br />";}
?>
</body>
</html>

a slight mod to above; following two lines should pull the session path from the environment so you don't have to know what the path is.  They would replace line 12 above:
$sessionpath = session_save_path();
$sessfile=$sessionpath."/sess_".$sid;
