PHP文件删除权限被拒绝

Question

I need to delete files in php and i keep getting this error: N.B : I noticed that all files are deleted except one that causes the error:

Warning: unlink(c:/wamp/www/EmploiPublic/app/Resources/sessions/sess_f0g4jsreposgbv6dkt36sud0v6): Permission denied

$files = glob('c:/wamp/www/EmploiPublic/app/Resources/sessions/*'); // get all file names
foreach($files as $file){ // iterate files
   chown($file, 0777);
   chmod($file, 0777);
   if(is_file($file)){
      unlink($file); // delete file
   }
}

Answer 1

Your chown is not correct.

http://php.net/manual/en/function.chown.php

The second parameter is die username or userid.
