嗨,如果不创建新文件并保存,我正在尝试将数据附加到现有文件中。相反,我的代码将数据保存了一次。下一个数据集只是覆盖第一个。请帮我弄清楚我做错了什么......

评论后我更改了代码,现在我得到了 警告:DOMDocument::load() [domdocument.load]: Extra content at the end of the document in

    function toXml($reg)
    {

        $xmlFile = "customers.xml";
        $doc = new DomDocument('1.0');
        $doc->load( $xmlFile);

        $cusCart = $doc -> createElement('cusCart');
        //$cusCart = $doc->appendChild($cusCart);

        foreach ($reg as $item => $val )

        {
            $customer = $doc->createElement('customer');
            $customer = $cusCart->appendChild($customer);

            $cusId = $doc->createElement('cusId');
            $cusId = $customer->appendChild($cusId);
            $value = $doc->createTextNode($item);
            $value = $cusId->appendChild($value);


            $fName = $doc->createElement('fName');
            $fName = $customer->appendChild($fName);
            $value1 = $doc->createTextNode($val["fName"]);
            $value1 = $fName->appendChild($value1);

            $lName = $doc->createElement('lName');
            $lName = $customer->appendChild($lName);
            $value2 = $doc->createTextNode($val["lName"]);
            $value2 = $lName->appendChild($value2);

            $phone = $doc->createElement('phone');
            $phone = $customer->appendChild($phone);
            $value3 = $doc->createTextNode($val["phone"]);
            $value3 = $phone->appendChild($value3);


            $email = $doc->createElement('email');
            $email = $customer->appendChild($email);
            $value4 = $doc->createTextNode($val["email"]);
            $value4 = $email->appendChild($value4);


            $pwd = $doc->createElement('pw');
            $pwd = $customer->appendChild($pwd);
            $value5 = $doc->createTextNode($val["pw"]);
            $value5 = $pwd->appendChild($value5);


        }

        $cusCart = $doc->appendChild($cusCart);     
        $doc->save($xmlFile);

        $strXml = $doc->saveXML();
        echo("<br>----- DATA RECOREDED!!! ----");

        return $strXml;
    }

在将子节点和属性附加到其父节点之前,应将其添加到节点。请尝试以下

function toXml($reg){
    $doc = new DomDocument('1.0');
    $doc->load( 'cusXML.xml');

    $cusCart = $doc -> createElement('cusCart');
    foreach ($reg as $item => $val )
    {
        $customer = $doc->createElement('customer');

        // Create cusId node
        $cusId = $doc->createElement('cusId');
        $value = $doc->createTextNode($item);
        $value = $cusId->appendChild($value);
        $cusId = $customer->appendChild($cusId);

        // Create pw node
        $pwd = $doc->createElement('pw');
        $value5 = $doc->createTextNode($val["pw"]);
        $value5 = $pwd->appendChild($value5);
        $pwd = $customer->appendChild($pwd);

        $customer = $cusCart->appendChild($customer);
    }

    $cusCart = $doc->appendChild($cusCart);

    if(file_exists('cusXML.xml')) { $doc->save("cusXML.xml"); }
    else{ $doc->save("cusXML.xml"); }

    $strXml = $doc->saveXML();
    echo("<br>----- DATA RECOREDED!!! ----");
    return $strXml;
}

您可能有一个附加的texttag结束后的 XML 文档。像

<?xml version="1.0"?>
<document>
    <article>sample</article>
</document>
</xml>

所以只需删除root元素后的其他文本。在上面的示例中,根元素是</document>,其他文本或元素是</xml>

由于您正在动态生成 XML,因此在进一步处理之前首先检查您的 XML,并在根元素结束后识别其他文本。

这是由于 xml 文件格式错误造成的。我的 xml 文件是

<cusCart> <customer> <cusid>...</cusid> </customer> </cusCart>

在我的代码上,我每次都调用(根元素)。所以每次我追加 <cusCart> <customer> <cusid>...</cusid> </customer> </cusCart><cusCart> <customer> <cusid>...</cusid> </customer> </cusCart>都会发生

相反,我必须调用 root 一次来附加<customer> <cusid>...</cusid> </customer><customer> <cusid>...</cusid> </customer>感谢您的提示!
