Phpftp fails to upload multiple files

Phpftp fails to traverse folders when uploading multiple files. it is intended to upload files to FTP in batches. There are two arrays, dir and files, one is the directory array and the other is the file array.
Failed to upload via ftp. there is no problem with a single upload ??? How can this problem be solved?

foreach ($li['files'] as $i){$c+=1;$ftp->upload($i,$i);if($c>= count($li['files'])/2){set_time_limit(300);}}

Have you created a directory?

Have you created a directory?
Yes. The first file seems to be okay, but it will not work in the future.

I didn't see it.

This is a php ftp class found on the internet. a folder Traversal function is added. uploading a single file is fine. if foreach is used, no error output is returned,
VAR_DUMP has no output either. it is okay to add a number of entries such as below. it can be uploaded,

$ftp->upload('smx/ewm/ewm.html','smx/ewm/ewm.html');

However, even the error output ($ this-> _ error ("ftp_unable_to_upload: localpath [". $ localpath. "]/remotepath [". $ remotepath. "]");) none

foreach ($li['files'] as $i){$c+=1;$r = $ftp->upload($i,$i);if($r){echo 'ok- '.$i.'
';}else{echo 'fail- '.$i.'
';}}
