}
// Creating a new XML using DOMDocument
$file_list = new DOMDocument('1.0');
$xml_root = $file_list->createElement('filelist');
$xml_root = $file_list->appendChild($xml_root);
// Setting the 'currentPath' attribute of the XML
$current_path = $file_list->createAttribute('currentPath');
$current_path->appendChild($file_list->createTextNode($current_dir));
$xml_root->appendChild($current_path);
// Replacing the word 'root' with the real root path
$current_dir = substr_replace($current_dir, $root, 0, 4);
$di = new DirectoryIterator($current_dir);
// Creating the XML using DirectoryIterator
while($di->valid())
{
if(false == $di->isDot())
{
if($di->isDir() && true != in_array($di->getBasename(),$h_folders))

Answer 1

The & character is used in HTML to write entities.
If you want to display arbitrary text in HTML, you need to escape it by calling htmlentities().

Answer 2

If you give some source I can help, file content not file name.
Example how get list of files:
$c = "/some/path/to/file/here";
if(is_dir($c)){
foreach(scandir($c) as $file){
if($file != '.' && $file != '..'){
$d = $c.DIRECTORY_SEPARATOR.$file;
echo " \"". realpath($d) ."\"\n";
}
}
}
