Query WMI remotely with PHP

Question

My current code looks like this:

define ( 'CPU_NAME', 'remote_server' );
$obj = new COM ( 'winmgmts:{impersonationLevel=impersonate}//' . CPU_NAME . '/root/cimv2' );
if ( is_object ( $obj ) ){ 
     $process = $obj->execquery ( "SELECT * FROM Win32_Process" );
}

Where would I put the login credentials for the remote_server? I see that it would take a username and password, but I'm not sure how to implement that.

Any help would be appreciated.

<?php
    $obj = new COM ( 'winmgmts://localhost/root/CIMV2' );
    $fso = new COM ( "Scripting.FileSystemObject" );    
    $wmi_computersystem    =    $obj->ExecQuery("Select * from Win32_ComputerSystem");
    $wmi_bios              =    $obj->ExecQuery("Select * from Win32_BIOS");
    $processor             =    $obj->ExecQuery("Select * from Win32_Processor");
    $PhysicalMemory        =    $obj->ExecQuery("Select * from Win32_PhysicalMemory");
    $BaseBoard             =    $obj->ExecQuery("Select * from Win32_BaseBoard"); 
    $LogicalDisk           =    $obj->ExecQuery("Select * from Win32_LogicalDisk");


    foreach ( $wmi_computersystem as $wmi_call )

    }

<?php
    $strComputer = "YOURREMOTEHOST";
    $objSWbemLocator = new COM ("WbemScripting.SWbemLocator");
    $objSWbemServices = $objSWbemLocator->ConnectServer($strComputer, "root\cimv2", "DOMAIN\USER", "Password");
    $objSWbemServices->Security_->ImpersonationLevel = 3;
    $obj = $objSWbemServices;
    $fso = new COM ( "Scripting.FileSystemObject" );

CONNECTING

For global admins

define("NAMECOMP", 'COMP1'); // COMP1 - name or ip of local or remote computer 
$WMI= new COM ( 'winmgmts:{impersonationLevel=impersonate}//'. NAMECOMP.'/root/cimv2' ); 

For with login and password

$objLocator = new COM("WbemScripting.SWbemLocator");
$objService = $objLocator->ConnectServer(
                'ComputerName', //name/ip remote/local comp
                "root\cimv2",
                'login', //login remote/local comp
                'password', //password remote/local comp
                "MS_409",
                "ntlmdomain: YourDomain" //domain remote/local comp
            );

GET INFORMATION

$CountCore=0;
foreach ($WMI->instancesof ( 'Win32_Processor' ) as $proc ) {
  ++$CountCore;
}
echo 'Count Core = ' . $CountCore; 

add information of speed and socket processor

$CountCore=0;
foreach ($WMI->instancesof ( 'Win32_Processor' ) as $Processor) {
  ++$CountCore;
  $Speed=$Processor->CurrentClockSpeed;
  $Socket=$Processor->SocketDesignation;
}
echo 'count core = '.$CountCore;
echo 'speed = ' . $Speed. 'Mhz';
echo 'socket = '.$Socket; 

get other information simple - just replace class for instancesof ('Win32_Processor')

Information of classes WMI

SEND COMMAND

if ((($_GET['Reboot']==1) OR ($_GET['Shutdown']==1))) { 
 
  define("NAMECOMP", 'COMP1');
          
  $WMI= new COM('winmgmts:{impersonationLevel=impersonate,(Shutdown)}//'. NAMECOMP.'/root/cimv2'); 
  
  foreach($WMI->instancesof('Win32_OperatingSystem') as $mp)  {
      if ($_GET['Reboot']==1) {
          $mp->Reboot; 
      }
      if ($_GET['Shutdown']==1) {
          $mp->Shutdown; 
      }
}

I know this thread is not the newest but maby this info helps someone. If you try to read or write Registy keys or installed Software class on a Remote Computer you need to pass the Architecture under the query should run. You can use something like this.

function Connect($server = "RemotePC",$namespace = "root/CIMV2",$impersonate = 3,$Architecture = 64,$userid = null,$password = null){
        try {
            $wbemnvs = new COM("WbemScripting.SWbemNamedValueSet");
            $wbemnvs->add("__ProviderArchitecture", $Architecture);
            $wbemnvs->add("__RequiredArchitecture", true);
            $wmiLocator = new COM("WbemScripting.SWbemLocator");
            $this->wmiNameSpace = $wmiLocator->ConnectServer($server, $namespace, $userid, $password,null,null,128,$wbemnvs);
            if($this->wmiNameSpace){
                $this->ConnectedServer = $server;
            }else{ return false; }
            if($impersonate){
                // mehr infos: http://msdn.microsoft.com/en-us/library/aa393618%28v=vs.85%29.aspx
                $this->wmiNameSpace->Security_->ImpersonationLevel = $impersonate;
            }
            return true;
        }
        catch(Exception $e){
            $this->wmiNameSpace = NULL;
            return false;
        }
    }
