php - Delete unziped files -

i have problem script. when unzip use tis script

if (file_exists($zipfile)) {     $zip = new ziparchive;     if ($zip->open($zipfile) === true)     {         if ($zip->extractto($path) === true)             return 'file extracted';         else             return 'cant extract';         $zip->close();     }     else     {         return 'cant open file 2';     } } else {     return 'zip doesnt exist'; } 

i can't delete extracted file use ftp. folder($path) have chmode 777 when try delete extracted file use ftp see message permission denied if upload files folder use ftp can delete file

as dahaka said, zip-close(); never called, either return 'file extracted' or 'cant extract' before reaching zip-close();, exiting method. should make zip-close(); come before returns in code
