I'm trying to open a directory and create an XML file based on the
folder & file structure. Here is my code:

function imagefolder($imagedir,$level) {

if ($dir = opendir($imagedir)) {
        $xmlcode = "";
        $spacer = str_repeat(' ',$level);
        while (($file = readdir($dir)) != false ) {
                                if ($file != ".") {
                                        if ($file != "..") {
                                               if (is_dir($dir ."/". $file)) {
                                                        echo("level is $level and file is $file and dir is $dirS");
                                                        $xmlcode = $xmlcode + $spacer + "<group id='".$level."'
title='".xmlReady($file)."'>".imagefolder($dir ."/".
$file,$level+1)."</group>\n";
                                                }
                                                   else {
                                                                if (substr(strtolower($file,-3) == 'jpg')) {
                                                                $imageinfo = getimagesize($file);
                                                                $width = $imageinfo[0];
                                                                $height = $imageinfo[1];
                                                                $size = round(filesize($file)/1024,1).' KB';
                                                                $xmlcode = $xmlcode + $spacer +"<image id='".$level."'
title='".xmlReady($file)."' src='".$imagedir.$file."'
width='".$width."' height='".$height."' comments='".xmlReady($file)."'
/>\n";
                                                                }

                                                }
                                        }
                                }
        }
        closedir($dir);

}
        return $xmlcode;
}

function jsalert($msg) {
echo ("<script language='javascript'>");
echo ("alert('".$msg."');");
echo ("</script>");

}

function xmlReady($str){
$str = str_replace("&", "&amp;",$str);
$str = str_replace("<", "&lt;",$str);
$str = str_replace(">", "&gt;",$str);
$str = str_replace("'","&apos;",$str);
$str = str_replace("\"", "&quot;",$str);
return $str;
}

////////////////////////////////////////////////////////////// DISPLAY
XML

header("Content-type: application/xml");
echo("<?xml version='1.0'?>\n");
echo("<catalog>\n");
//echo(display_children(0,0,$dbTable));
echo(imagefolder("./",0));
echo("</catalog>");

can anybody help me with this??? The output is basiclly just <catalog>
</catalog> sometimes I can get it to read just the folder and they do
display well inside of catalog elements.
