PHP, WMI, COM object and getting the array value

This code

      define ( 'CPU_NAME', '.' );

      $obj = new COM ( 'winmgmts:{impersonationLevel=impersonate}//' . CPU_NAME . '/root/cimv2' );

      if ( is_object ( $obj ) )
      {
            $process = $obj->execquery ( "SELECT * FROM Win32_BIOS" );

            if ( $process->count > 0 )
            {
                  foreach($process as $row){
                  	echo"BIOS: $row->bioscharacteristics<br />";
                  }
            }
            else
            {
                  echo 'error';
            }

            $obj = null;
      }
      else
      {
            echo 'no object';
      }

Open in new window


produces an error

Catchable fatal error: Object of class variant could not be converted to string in C:\xampp\htdocs\aa\index.php on line 71

I'm aware of the WMI classes and the property value of the BIOS characteristics as it is an array of integers separated with "," - or maybe just string value of integers with ",". Most of the Win32 classes does not give this error (Win32_Account for example). Caould you guide me how to deal with these kind of situations ?

I have never done anything with PHP, but as far as doing this in VBScript or PowerShell I would usually join this particular property array into a single string and then use it.
[string]::Join(",",(GWMI -Q "SELECT bioscharacteristics FROM Win32_BIOS").BiosCharacteristics)

Open in new window

I'm assuming in PHP you can do something similar?

Thanks for response, I'll try to convert it to PHP and get back to you.

Well, partially. Made me code some more to finally get the value into an array.
