I use the COM object of PHP to access to WMI Win32_PingStatus for create a remote ping. It's impossible to obtain the result of my request:

My Error:

Unable to lookup `statuscode': Unknown Name.

Test script:
My Class:

class Windows
	protected $servers;
	protected $username;
	protected $password;
    public function __construct($servers, $username, $password)
		$this->servers = $servers; 
		$this->username = $username;
		$this->password = $password;
	protected function services($command)
		$services = (new \COM ("WbemScripting.SWbemLocator"))->ConnectServer($this->servers, $command, $this->username, $this->password);
		$services->Security_->AuthenticationLevel = 3;
		$services->Security_->ImpersonationLevel = 3;
		return $services;
	public function getHosts()
        return $this->services('root\\cimv2')
		->ExecQuery('Select * from Win32_ComputerSystem');

    public function GetPing($srv)
        return $this->services('root\\cimv2')
            ->ExecQuery('select * from Win32_Pingstatus where Address='.$srv.'');

And my View:

$servername = '';

        $vmadress = new \Windows($servername, 'Ceicom-Cloud\Administrateur', 'Ceicom3333');
        $pings = $vmadress->getPing('');

        foreach ($pings->statuscode as $ping)

I have tested my class with my function getHosts and it's Ok !

Expected result:
If i user the PowerShell for Win32_PingStatus (With the same code) i have the return of statuscode...

Sorry, but your problem does not imply a bug in PHP itself.  For a
list of more appropriate places to ask for help using PHP, please
visit as this bug system is not the
appropriate forum for asking support questions.  Due to the volume
of reports we can not explain in detail here why your report is not
a bug.  The support channels will be able to provide an explanation
for you.

Thank you for your interest in PHP.

I can tell you right now that $srv needs quotes in the query and $pings will be a collection. Check that your PHP code correctly matches up with your PowerShell commands.
