使用DOMDocument（）在php中創建XML文件

Question

我想在php中創建XML文件，並將值從數組保存到變量

<?php
$name = $e['name_1'];
$email = $e['email_id'];
$phone_no =$e['phone_no'];

$doc = new DOMDocument();
$doc->formatOutput = true;

$ele1 = $doc->createElement('StudentName');
$ele1->nodeValue=$name;
$doc->appendChild($ele1);

$ele2 = $doc->createElement('FatherEmailId');
$ele2->nodeValue=$email;
$doc->appendChild($ele2);

$ele3 = $doc->createElement('PhoneNumber');
$ele3->nodeValue=$phone_no;
$doc->appendChild($ele3);

$doc->save('MyXmlFile007.xml');  

?>

我想要我的XML格式

<?xml version="1.0"?>
<StudentDetails>
<StudentName>Pravin Parayan</StudentName>
<FatherEmailId>pravinp@pigtailpundits.com</FatherEmailId>
<PhoneNumber>9000012345</PhoneNumber>
<StudentDetails/>

但是我得到的不是上面的東西

<?xml version="1.0"?>
<StudentDetails/>
<StudentName>Joel George</StudentName>
<FatherEmailId>joy@pigtailpundits.com</FatherEmailId>
<PhoneNumber>9000012345</PhoneNumber>

Answer 1

您需要做的就是添加根元素StudentDetails，並將所有其他元素添加到其中，如下所示：

<?php
$name = $e['name_1'];
$email = $e['email_id'];
$phone_no =$e['phone_no'];

$doc = new DOMDocument();
$doc->formatOutput = true;

$root = $doc->createElement('StudentDetails');
$root = $doc->appendChild($root);

$ele1 = $doc->createElement('StudentName');
$ele1->nodeValue=$name;
$root->appendChild($ele1);

$ele2 = $doc->createElement('FatherEmailId');
$ele2->nodeValue=$email;
$root->appendChild($ele2);

$ele3 = $doc->createElement('PhoneNumber');
$ele3->nodeValue=$phone_no;
$root->appendChild($ele3);

$doc->save('MyXmlFile007.xml');

結果將是：

<?xml version="1.0"?>
<StudentDetails>
  <StudentName>Pravin Parayan</StudentName>
  <FatherEmailId>pravinp@pigtailpundits.com</FatherEmailId>
  <PhoneNumber>9000012345</PhoneNumber>
</StudentDetails>
