function CreateStatus($status) { $root = $this->dom->createElement('root'); $this->dom->appendChild($root); //创建status标签 $statusInfo = $this->dom->createElement('status'); $root->appendChild($statusInfo); $statusInfoValue = $this->dom->createTextNode($status); $statusInfo->appendChild($statusInfoValue); //输出XML数据 return $this->dom->saveXML(); }
