Hi
 This is the code for remove the unwanted charecter from the uploaded file

 $_FILES['image']['name'] = strtolower(trim($_FILES['image']['name']));
                 $_FILES['image']['name'] = str_replace(array('\'',' ','\#','\$','\&','\!','\@','\#','\$','\%','\^','\&','\*','\(','\)','\_',
              '\+','\{','\}'),'', $_FILES['image']['name']);
