Displaying the time of the Latest Update to an ISAM table

[boclair <boclair@xxxxxxxxxxxxxx>]

PHP 4.3.10
MySql 4.0.20

How do I find and then display on a web page the time that additional 
data added to, or,  existing data amended in an ISAM table?

My latest futile attempt , with connection made and the database already 
selected,

<?PHP
$logged = mysql_query("SHOW TABLE TABLE UPDATE_TIME from  members");
if (!$logged) {$logged="not found";}
else {$logged=$logged;}
?>
<p>Last logged: <?PHP =$logged;?></p>

With no errors reported, the display is "not found".
