How can PHP be used to retrieve the bandwidth usage of a Windows server?

To retrieve the bandwidth usage of a Windows server using PHP, you can utilize the Windows Performance Counters. By accessing the appropriate performance counter related to network usage, you can retrieve the data and display it in your PHP script.

$server = 'localhost';
$networkInterface = 'Local Area Connection'; // Name of the network interface
$counter = "\\Network Interface($networkInterface)\\Bytes Total/sec";

$wmi = new COM("winmgmts:{impersonationLevel=impersonate}//$server");
$networkData = $wmi->ExecQuery("SELECT * FROM Win32_PerfFormattedData_Tcpip_NetworkInterface WHERE Name='$networkInterface'");

foreach ($networkData as $data) {
    echo "Current Bandwidth Usage: " . $data->BytesTotalPersec . " bytes/sec";
}
