我的代码始终有效，它与您的方法有所不同，我希望它能为您提供帮助。

$imgpath='uploads/profile_pic/';
            $all_img="";
            if($_FILES["profile_pic"]['name'])//form input type file
            {         
               $path_parts = pathinfo($_FILES["profile_pic"]["name"]);
               $image_path = $path_parts['filename'].'_'.time().'.'.$path_parts['extension']; 
               $all_img.=$image_path;
               move_uploaded_file($file_tmp=$_FILES["profile_pic"]["tmp_name"],$imgpath."/".$image_path);
               $data['cm_user_profile_pic']=$all_img;//store image name in array
            }
