Please check my code.

**questions.php**

```
<?php
include("db.php");

$dom = new DOMDocument("1.0");
$node = $dom->createElement("questions");
$parnode = $dom->appendChild($node); 

$week = date("W");
$query = "SELECT * FROM ".QUIZ_QUESTION." WHERE week='".$week."'";  
$result = mysql_query($query);

header("Content-type:  application/xml; charset=ISO-8859-1"); 

while ($row = mysql_fetch_assoc($result)){  
  $node = $dom->createElement("question");  
  $question = $parnode->appendChild($node); 
  $ansAtrribute = $question->setAttribute("id",$row['id']);

  $que = $dom->createElement("que",$row['question']);
  $quenode = $question->appendChild($que);

  $qryOpt = mysql_query("SELECT * FROM ".QUIZ_OPTION." WHERE question_id='".$row['id']."'");
  while($gerOptions = mysql_fetch_array($qryOpt)){
  $ans = $dom->createElement("ans",$gerOptions['option']);
  $ansNode = $question->appendChild($ans);
  $ansAtrribute = $ansNode->setAttribute("ans",$gerOptions['is_correct']);
  }
} 
echo $dom->saveXML();
?>

```

I am directly run the `questions.php` here is the XML output:

**Output:**

```
-<questions>
  -<question id="1">
    <que>What is PHP?</que>
    <ans ans="0">Fruit</ans>
    <ans ans="1">Language</ans>
    <ans ans="0">Game</ans>
  </question>
</questions>

```

**quiz.php**

```
<?php
    $xmlDoc = new DOMDocument("1.0");
    $xmlDoc->load("questions.php");

    $questions = $xmlDoc->getElementsByTagName("question");
    $question= $questions->item($qnum)->getElementsByTagName("que")->item(0)->nodeValue;
    $ans1= $questions->item($qnum)->getElementsByTagName("ans")->item(0)->nodeValue;
    $ans1r= $questions->item($qnum)->getElementsByTagName("ans")->item(0)->getAttribute('ans');
    $ans2= $questions->item($qnum)->getElementsByTagName("ans")->item(1)->nodeValue;
    $ans2r= $questions->item($qnum)->getElementsByTagName("ans")->item(1)->getAttribute('ans');
    $ans3= $questions->item($qnum)->getElementsByTagName("ans")->item(2)->nodeValue;
    $ans3r= $questions->item($qnum)->getElementsByTagName("ans")->item(2)->getAttribute('ans');
?>

```

I am running the `quiz.php` but the `questions.php` doesn't load.

I am getting following error:
