This piece of code generates a last updated message. It iterates through the directory and finds the newest file with a PHP file extension
<?
// open directory
$myDirectory = opendir(".");
$Newest = 0;
// get each entry
while($entryName = readdir($myDirectory))
{
if(strpos($entryName, ".php") > 0)
{
$Newest = max($Newest, filemtime($entryName));
}
}
print("<div CLASS=Footer>Site updated ");
print(date("jS M Y", $Newest));
print("</div>");
// close directory
closedir($myDirectory);
?>
