多文件上传其实就包括了图片及各种文件了，下面介绍的是一款PHP多文件上传类，一共两个文件，upp.php 和 uploadFile.php,upp.php,这是前台所显示的表单文件了，默认的是四个上传文件域，我们可以手动进行修改，另外这个页面嵌套了 uploadFile.php 文件上传类，下面一起来看例子。<?php
header('content-type:text/html;charset=utf-8');
require('uploadFile.php');
if(isset($_POST['submit'])){
$uploads=$_FILES['file'];
$num_file=count($uploads['name']);
$up=newUploadFile($uploads,'uploads',1024);
$num=$up->upload();
if($num==$num_file){
echo'全部文件上传成功';
exit;
}else{
echo$num,'个文件上传成功
';
echo$up->showErrorInfo();
exit;
}
}
