Content on log files via browser

I’ve a client that runs special program on about 100 servers. This program writes a log on central server every 3 minutes. So, when I checked main server, I found a directory Logs (C:\Logs). Log’s directory contains many log files (each log for each server). On this server installed and runs a web server, Apache ;). So, I’d like to show a small AppsRuns.php file, which stored on web server. If we go to the http://server1/AppsRuns.php we will see a content of each log file on one web page. This web page refreshing every 10 sec. Here is a content of AppsRuns.php file:

    $refresh_time = 10; // seconds
    $path = "C:\LOGS";

    header("Content-Type: text/plain");
    header("Refresh: $refresh_time");
   

    if($handle = opendir($path)) {
    while (false !== ($file = readdir($handle))) {
        $pi = pathinfo($path . '/' . $file);
        if($pi['extension'] === 'txt') {
        include($path . '/' . $file);
        }
    }
    }
?>
