我有一个上传功能,可以处理一个或多个文件,这些文件能够上传到一个文件夹,然后将一个索引插入 mysql。如何将多个图像存储为数组?
//This upload code to allow users to upload specific files
<?php
$user_id = $_SESSION['lt_user_id'];
$user_code = $_SERVER['AUTH_USER'];
if(isset($_FILES['files'])){
$errors= array();

$file_tmp =$_FILES['files']['tmp_name'][$key];
$file_type=$_FILES['files']['type'][$key];
if($file_size > 2097152){
$errors[]='File size must be less than 2 MB';
