php 多文件上传经典代码
<?php
require_once ("include/upload.class.php");
if ($_POST["button"]) {
//print_r($_FILES);
//多个上传
//$upload = new TTRUpload($_FILES,"ANY");//同下
$upload = new TTRUpload(array(
$_FILES["file1"],
$_FILES["file2"],
$_FILES["file3"],
$_FILES["file4"]
) , "ANY");
//单个上传
//$upload = new TTRUpload($_FILES["file1"]);
$upload->upload();
echo $upload->getUploadFileName();
}
