PHP操作COM的问题

[yanxw_227]

PHP调用COM组件，需求是要读取进程的用户名，但是GetOwner这个函数(method)的输出是在参数中的([out]类参数)，PHP好像没有这种用法，请教各位高人了！多谢！

<?
$objLocator   =   new   COM("WbemScripting.SWbemLocator");  
$wmi   =   $objLocator->ConnectServer();  

$kkk =array('Caption','ExecutablePath');
$lll = array('GetOwner');
$buffer = _GetWMI($wmi, "Win32_Process", $kkk, $lll);

echo '<pre>';
print_R($buffer);
echo '</pre>';

function _GetWMI($wmi,   $strClass,   $strValue   =   array(), $strMethod = array()   )   {  
	$objWEBM   =   $wmi->Get($strClass);
    if(   PHP_VERSION   <   5   )   {  
        $objProp   =   $objWEBM->Properties_;  
        $arrProp   =   $objProp->Next($objProp->Count);  
        $objMeth   =   $objWEBM->Methods_;  
        $arrMeth   =   $objMeth->Next($objMeth->Count);  
        $objWEBMCol   =   $objWEBM->Instances_();  
        $arrWEBMCol   =   $objWEBMCol->Next($objWEBMCol->Count);
    }   else   {  
        $arrProp = $objWEBM->Properties_;
		$arrMeth = $objWEBM->Methods_;
        $arrWEBMCol = $objWEBM->Instances_();
    }
    foreach($arrWEBMCol   as   $objItem) {  
		//reset($arrProp);  
		$arrInstance   =   array();  
		foreach($arrProp   as   $propItem) {
			eval("\$value   =   \$objItem->"   .$propItem->Name   .";");  
			if(   empty(   $strValue   )   )   {  
				$arrInstance[$propItem->Name]   =   trim($value);
			} else {  
				if(   in_array(   $propItem->Name,   $strValue   )   )   {  
					$arrInstance[$propItem->Name]   =   trim($value);  
				}
			}
		}
		foreach($arrMeth as $i=>$methItem) {
			if(is_array($strMethod) and count($strMethod)>0) {
				if(in_array($methItem->Name,$strMethod)) {
					eval("\$value2   =   \$objItem->".$methItem->Name."();");  
					$arrInstance[$methItem->Name] = trim($value2);
				}
			}
		}
		$arrData[]   =   $arrInstance;  
    }  
    return   $arrData;  
}
?>

PHP也有out作为参数的，比如preg_match_all函数。

你贴代码出来想问什么？
