我有一个代码可以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。 我写了代码，工作正常。 我需要的帮助是如何编写代码，使得代替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载到它们各自的不同文件夹中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

$l = strlen($str) - $i;
$ext = substr($str,$i+1,$l);

创建一个接受帖子文件的函数，并在调整大小并在其返回后写入一组文件信息。然后在文件验证后为每个帖子文件调用它。 如果它返回一个没有错误的信息数组。然后这里的数据库工作人员就是一个例子
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
}
}
