我有一个代码，将不同的图像文件上传到服务器上的不同文件夹，并在mysql数据库的不同字段中存储文件名。我已经写了代码，它的工作很好。我需要的帮助是如何编写代码，而不是使用多个代码块来重新调整大小和上传每个图像，一个代码块将能够重新调整多个图像的大小，但仍然将多个图像上传到各自不同的文件夹中，同时仍然在mysql数据库的不同字段中存储不同的文件名。如有任何帮助，我将不胜感激。
下面是php代码:<?php

创建一个接受post FILE的函数，并在调整大小和写入后返回一个文件信息数组。然后在文件验证后对每个post File调用它。如果它返回一个没有错误的信息数组。然后做数据库工作人员这里是一个例子
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
}
}
