php多文件上传多图片上传程序代码-php教程

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文件上传例子,代码如下:

<?php
header('content-type:text/html;charset=utf-8');
require('uploadFile.php');
if(isset($_POST['submit'])){
$uploads = $_FILES['file'];
$num_file = count($uploads['name']);
$up = new UploadFile($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<br/>';
echo $up->showErrorInfo();
exit;
}
}
?>
