关注此帖Saving form data to an existing XML-file using PHP

我想知道如何将多个变量保存到xml文件中。使用描述的方法，我只能保存最后一个。

我发现了一种按我想要的方式工作

$xml="\n\t\t<Bares>\n\t\t";     
    {
        while ($stmt->fetch()){ 

                $xml .="<Bar>\n\t\t";
                $xml .= "<nome>".$nome."</nome>\n\t\t";
                $xml .= "<morada>".$morada."</morada>\n\t\t";
                $xml .= "<nif>".$nif."</nif>\n\t\t";
                $xml .= "<telefone>".$telefone."</telefone>\n\t\t";
                $xml .= "<email>".$email."</email>\n\t\t";
                $xml .= "<imgid>".$imgid."</imgid>\n\t\t";
                $xml.="</Bar>\n\t";

        }

            $xml.="</Bares>\n\r";

            $doc = new DOMDocument('1.0');
            $doc->formatOutput = true;
            $doc->preserveWhiteSpace = true;
            $doc->loadXML($xml, LIBXML_NOBLANKS);
            $doc->save('dados.xml');

但我希望能够编辑xml标头标签（xml版本=＆＃34; 1.0＆＃34;？），我不能这样做

再次考虑使用DOMDocument()方法，而不是使用字符串连接构建XML。使用PHP的信息手册，下面显示了如何添加Document Type Declaration (DTD)和XSLT processing line：

// Create an instance of the DOMImplementation class
$imp = new DOMImplementation;    
// Create a DOMDocumentType instance
$dtd = $imp->createDocumentType('graph', '', 'graph.dtd');

// Create a DOMDocument instance
$doc = $imp->createDocument();    
// Set other properties
$doc->encoding = 'UTF-8'; $doc->standalone = true;
$doc->formatOutput = true; $doc->preserveWhiteSpace = true;

// Create an XSLT adding processing line
$xslt = $doc->createProcessingInstruction('xml-stylesheet', 
                                          'type="text/xsl" href="base.xsl"');    
// Append XSLT instruction to the doc
$doc->appendChild($xslt);
// Append DTD to the doc
$doc->appendChild($dtd);

// Create root
$root = $doc->appendChild($doc->createElement('Bares'));

// Iteratively append the elements (with values)
while ($stmt->fetch()){                        
    $barNode = $root->appendChild($doc->createElement('bare'));
    $nomeNode = $barNode->appendChild($doc->createElement('nom', $nome));
    $moradaNode = $barNode->appendChild($doc->createElement('morada', $morada));                
    $nifNode = $barNode->appendChild($doc->createElement('nif', $nif));
    $telefoneNode = $barNode->appendChild($doc->createElement('telefone', $telefone));
    $emailNode = $barNode->appendChild($doc->createElement('email', $email));
    $imgidNode = $barNode->appendChild($doc->createElement('imgid', $imgid));          
}

$doc->save('dados.xml');

我希望能够编辑xml标头标签
