我有一个代码，可将不同的图像文件上传到服务器上的不同文件夹，并将文件名存储在mysql数据库的不同字段中。我已经编写了代码及其工作正常。我需要的帮助是如何编写代码，这样一个代码块可以重新调整多个图像的大小，但仍可以将多个图像上传到它们各自的不同文件夹中，而不是使用多个代码块重新调整大小并上传每个图像并且同时仍将不同的文件名存储在mysql数据库的不同字段中。任何帮助将不胜感激。
以下是php代码：
<?php

创建一个接受发布FILE的函数，并在调整大小并写入后返回一个文件信息数组。然后在文件验证后针对每个发布文件调用该文件。如果它返回一个无错误的信息数组。那么这里的数据库人员是一个例子
function imageStaff($file){
// here resizing an writing staff
// return an array with index error and file information if no error then set this index to empty
}
//call here with post file
if(valid($_FILES['your_file')){ // valid is another function of yours to check if file size is ok, or check uploaded file_type etc
$array = imageStaff($_FILES['your_file']);
if(empty($array['error'])){
//do the db staff
}
}
