mysql - the path for the folder in my server (PHP) -

i have problem in php code.
have form let user upload files server, did not know how write correct path folder in server![enter image description here][1] want files store in, how path specific file download later.

the path in server : /public_html/upload_files

but keeps tell me :

warning: move_uploaded_file(upload_files/project_guidelines.pdf): failed open stream: no such file or directory in d:\sites\dwts.com\public_html\website\creat.php on line 50 warning: move_uploaded_file(): unable move 'c:\windows\temp\php14ac.tmp' 'upload_files/project_guidelines.pdf' in d:\sites\dwts.com\public_html\website\creat.php on line 50 error uploading file

code:

$len = count($_files['attachment']['name']);  for($i = 0; $i < $len; $i++) {  $uploaddir = 'upload_files/';  $filename = $_files['attachment']['name'][$i]; $tmpname = $_files['attachment']['tmp_name'][$i]; $filesize = $_files['attachment']['size'][$i]; $filetype = $_files['attachment']['type'][$i];  $filepath = $uploaddir . basename($_files['attachment']['name'][$i]);  $result = move_uploaded_file($tmpname,$filepath); if (!$result) {     echo "error uploading file";     exit; } 

thanx 😭

$uploaddir = 'upload_files/'; 

where drive? windows, needs drive:

$uploaddir = 'c:/upload_files/'; 

you can't give partial location second argument of move_uploaded_file...it needs full path.
