parsing html dom

[rpjd1971]

I want to compare document (table)id's to values in $POST.
The code I have is

$Ref  =$_POST['Ref'];
$source = file_get_contents( 'E:/wamp/www/Project/File.php' );
$document = new DOMDocument;
$document->validateOnParse = true; 
$document->file_get_html($source);
for($i=0; $i<count($Ref); $i++)
{
foreach($document->find('id') as $ID) 
{
if($ID == $Ref[$i])
{
echo "ok";
}
else
{
echo "no";
}
}
}

However I am getting
Fatal error: Call to undefined method DOMDocument::file_get_html()

I think the function you are looking for instead of file_get_html() is loadHTMLFile($source) (or saveHTMLFile($source) depending on what you actually want to do).

Also note that reading a .php file (versus requesting a URL from a webserver) is naturally just going to give you the raw contents of the script and not the rendered output that your web browser would see.
