错误类DOMElement的对象无法转换为字符串

Question

I am writing a new record to xml file with to item , A English word and a Hebrew word.

But the line
$newWord->appendChild($prop.$new_line);
causes this Error "Object of class DOMElement could not be converted to string"

the parameter $new_line equal to $new_line = " ";.

what I miss here thx ?

my code are:

<?php

  /*$wordH=$_GET['varHeb'];
  $wordE=$_GET['varEng'];*/
    $wordH="newhebWord";
    $wordE="newengWord";
  $new_line =  "
";

$doc='';

        if(!$doc)
        {
            $doc = new DOMDocument();
            // we want a nice output
            $doc->formatOutput = true;
            $doc->load('Dictionary_user.xml');
        }
        $Dictionary_user = $doc->documentElement;

        $newWord = $doc->createElement('newWord');



        $prop = $doc->createElement('Heb', $wordH);
        $newWord->appendChild($prop.$new_line);
        $prop = $doc->createElement('Eng',$wordE);
        $newWord->appendChild($prop.$new_line);


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

        $doc->save("Dictionary_user.xml");
    echo $doc->saveXML();


    ?>

You don't need to append a newline, you are dealing with a real data structure (A DOMDocument) not a string.
