How to unlink image in php?

Question

I am developing application in PHP. There is image folder. I want to delete image from the folder When user click on delete button. My code is running well. But the UNLINK() function not working. My code is

unlink('../photo_gallery/'.$image_name['imge_name'],777);

I am getting this error

Warning: unlink() expects parameter 2 to be resource,

and if i remove 777 then it shows

Warning: unlink(../photo_gallery/): Permission denied

Please suggest.

you dont need to pass `777` in unlink. set your `photo_gallery` folder to 777 — user2936213, Jan 21 '14 at 11:54
Two tips: 1) Stop typing random parameters unless functions no longer trigger warnings—that stuff is [documented](http://php.net/unlink) 2) If a program doesn't have permission to do something, it can't normally grant permissions to itself; that would beat the whole purpose of having permissions. — Álvaro González, Jan 21 '14 at 11:55

Just remove the second parameter. and try this

if ( is_file( '../photo_gallery/' . $image_name['imge_name'] ) ) {
   chmod ( '../photo_gallery/' . $image_name['imge_name'] , 777 );
   unlink ( '../photo_gallery/' . $image_name['imge_name'] );
}

try this

filename = '../photo_gallery/'.$image_name['imge_name'];

if(file_exists($filename))
{
  chmod($filename, 777);
  unlink($filename);
  echo "file has deleted";
}
else
{
 echo "file not exists";
}

Change the right on the folder. The server user running php must have rights on it to delete it.

The process in which you run your application (e.g. from Apache) needs to have write permission to the folder you want to delete from. check permission on "photo_gallery" folder

You are using this function wrong.

unlink('../photo_gallery/'.$image_name['imge_name']);

Be sure you have permision (chmod) on folder to write.
