Question

I have code which add item like below to xml file:

<newWord>
  <Heb>rer</Heb>
  <Eng>twew</Eng>
</newWord>

the problem is when I add element it will be not in the right place, it is out from xml tag like below.

<?xml version="1.0" encoding="UTF-8"?>
<xml>
  <newWord>
    <Heb>hebword</Heb>
    <Eng>banna</Eng>
  </newWord>
</xml>
<newWord>
  <Heb>rer</Heb>
  <Eng>twew</Eng>
</newWord>

How can I add the new element to correct place? thx

my code:

<?php    

    $wordH=$_GET['varHeb'];
    $wordE=$_GET['varEng'];


    $domtree='';

        if(!$domtree)
        {   
            $domtree = new DOMDocument('1.0', 'UTF-8');
            $domtree->formatOutput = true;
            $domtree->load('Dictionary_user.xml');
        }

        $Dictionary_user = $domtree->documentElement;

    $currentitem = $domtree->createElement("newWord");
    $currentitem = $domtree->appendChild($currentitem);

    $currentitem->appendChild($domtree->createElement('Heb', $wordH));
    $currentitem->appendChild($domtree->createElement('Eng',$wordE));

    $Dictionary_user->childNodes->item(0)->parentNode->insertBefore($currentitem,$Dictionary_user->childNodes->item(0));
        header("Content-type: text/xml");

    $domtree->save("Dictionary_user.xml");
    /* get the xml printed */
    echo $domtree->saveXML();
?>

Perhaps you want something like:

<?php 
if(!empty($_GET['varHeb']) && !empty($_GET['varEng'])){
    //Dont forget utf-8 if using Hebrew letters
    header('Content-type: text/xml; charset=utf-8');
    //Load It
    $xml = simplexml_load_file('./Dictionary_user.xml');

    //Add a new node & add the children
    $node = $xml->addChild('newWord');
    $node->addChild('Heb', trim($_GET['varHeb']));
    $node->addChild('Eng', trim($_GET['varEng']));


    //DOMDocument to format code output
    $dom = new DOMDocument('1.0', 'UTF-8');
    $dom->preserveWhiteSpace = false;
    $dom->formatOutput = true;
    $dom->loadXML($xml->asXML());

    echo $dom->saveXML();
}else{
    //params not set for $_GET
}

/**
 * Result
<?xml version="1.0" encoding="UTF-8"?>
<xml>
  <newWord>
    <Heb>hebword</Heb>
    <Eng>banna</Eng>
  </newWord>
  <newWord>
    <Heb>אנחנו אוהבים גלישת מחסנית</Heb>
    <Eng>We Love Stack overflow</Eng>
  </newWord>
</xml>
