Question

我在生成dompdf pdf时遇到问题。它渲染正确，但是当我尝试制作25页的pdf文件时，发生了php timout 30秒错误。

我通过正确设置imgpaths的domelement制作pdf。此外，它将值设置为2个字段。

我查了一下，结果发现，如果解析了一个新的body元素，dompdf会生成一个新页面。所以我为多个页面插入了多个正文。它渲染得很好，只需要很长时间，所以我可能做错了。

我的pdf生成代码如下：

    $pdf = Yii::app()->pfPDF->firstrun();
    $basepath = str_replace('\\', '/', Yii::app()->theme->basePath);

    $doc = new DOMDocument();
    $doc->preserveWhiteSpace = false;
    $htmlfile = $basepath.'/pdf/pdf.html';
    $html = null;
    \timestuff::$times[] = microtime(true);
    foreach($models as $model)
    {
        $model->printed = true;
        $model->save();
        $doc->loadHTMLFile($htmlfile);
        $html .= '<head>';
        $headNode = $doc->getElementsByTagName('head')->item(0);
        foreach($headNode->childNodes as $childnode){
            if($childnode->nodeType == XML_TEXT_NODE){
                continue;
            }
            $html.= $doc->saveHTML($childnode);
        }
        $html .= '</head><body>'; 
        $doc->getElementById('vouchercode')->nodeValue = $model->code;
        $doc->getElementById('timelimit')->nodeValue = $timelimit;
        $doc->getElementById('nllogo')->attributes->getNamedItem('src')->nodeValue = $basepath.'/pdf/assets/images/plate.png';
        $doc->getElementById('enlogo')->attributes->getNamedItem('src')->nodeValue = $basepath.'/pdf/assets/images/plate.png';
        $doc->getElementById('delogo')->attributes->getNamedItem('src')->nodeValue = $basepath.'/pdf/assets/images/plate.png';
        $doc->getElementById('frlogo')->attributes->getNamedItem('src')->nodeValue = $basepath.'/pdf/assets/images/plate.png';
        $doc->getElementById('customerlogo')->attributes->getNamedItem('src')->nodeValue = $basepath.'/pdf/assets/images/logo_krieghuus.png';
        $doc->getElementById('maxwifilogo')->attributes->getNamedItem('src')->nodeValue = $basepath.'/pdf/assets/images/maxwifi.png';
        $bodyNode = $doc->getElementsByTagName('body')->item(0);
        foreach($bodyNode->childNodes as $childnode){
            if($childnode->nodeType == XML_TEXT_NODE){
                continue;
            }
            $html.= $doc->saveHTML($childnode);
        }
        $html.= '</body>';
    }
    \timestuff::$times[] = microtime(true);
    Yii::app()->pfPDF->show($html);
    \timestuff::$times[] = microtime(true);
