PHP Upload Add domain name

function Ajaxfile () {

$upload _path = '/up ';

$rand = rand (100, 999);
$pics = Date ("Ymdhis"). $rand. '.' . $type;
$dir = Date ('/ymdh/');
$pic _path = $upload _path. $dir;
$pic _url = $pic _path. $pics;
if (!file_exists (path_root. $pic _path)) {
Creatfolder (path_root. $pic _path);
}
$PATH _root = Path_root. $pic _url;
Move_uploaded_file (lib_request:: $files [$filename] [' tmp_name '], $pic _path);
if (Request (' type ') = = ' goods ') {
Makethumbnail ($pic _path, $pic _path. ' _290x290.jpg ', 290, 190);
}
}
$arr [$filename] = Array (
' Name ' = $picname,
' Pic ' = $pic _url,
' Size ' = $picsize
);
}
echo Json_encode ($arr);
Exit ();
}

The path obtained after uploading is/up/xxxxx/xxxxx.jpg
I would like to change to: http://www.xxxx.com//up/xxxxx/xxxxx.jpg

An estimate is to want a change URL?

$pic _url = ' http://www.xxxx.com/'. $pic _path. $pics;

Is that so? The question is not clear haha.

If it's the path inside the database, you can update it.
If it is uploaded to a different server, this should not be
