在dom php中加载文件时出错

Question

I am using the below code to create a div <-- successfully. The problem is when i try to create a child div and select $pagenameselected.php to load. Here I get an error because when it loads $pagenameselected <-- it load the php script to create the div and not the created div like i can see in page source.

 <?php
 $myfile = fopen("../userfolders/$email/$ongrassdb/$pagenameselected.php", "w") or die("Unable to open file!");
 $x = "<?php " . '$dom' . "= new DOMDocument();" .
 '$element' . "= " . '$dom' . "->createElement('div', '$textcon');" .
 '$dom' . "->appendChild(" . '$element' . ");
 echo " . '$dom' . "->saveXML();?>";
 fwrite($myfile,$x);
 fclose($myfile);
 ?>

 $myfile = fopen("../userfolders/$email/$ongrassdb/$pagenameselected.php", "w") or die("Unable to open file!");
 $file = $DOCUMENT_ROOT. "../userfolders/$email/$ongrassdb/$pagenameselected.php";
 $doc = new DOMDocument();
 $doc->loadHTMLFile($file);
 //$elements = $doc->getElementsByTagName('div');

Answer 1

The class is expecting an HTML document, you are sending it a PHP document.

instead of using the $x =

You should just do this ...

$dom = new DOMDocument();
$ele = $dom->createElement('div', $textcon);
$dom->appendChild($ele);
$html = $dom->saveXML();

fwrite($myfile, $html);
