PHP多图上传

测试十图上传，不会出现重复文件！

admin_pic_upload.php 文件

<?php
include_once('admin_global.php');
 
if($_GET["AdminPurview"]!=""){
$db->Get_user_checkadmin($_COOKIE["AdminName"], $_COOKIE["password"], $_COOKIE["RndPassword"],$_GET["AdminPurview"]);
$Result = Trim($_GET["Result"]);
}
else{
echo "你没有处理该操作的权限";
    exit();
}
 
if($_POST['upload_submit']){
$pic_upload=$_POST['pic_upload'];
$pic_alt=$_POST['pic_alt'];
$pic_thumb=$_POST['pic_thumb'];
$thumb_width=$_POST['thumb_width'];
$thumb_height=$_POST['thumb_height'];
foreach($_FILES['pic_upload']['tmp_name'] as $key=>$value){
if(empty($value)){continue;}
$value_arr=array('');

//有图则上传图片

    $pic_thumb=intval($pic_thumb[$key]);
