本程序使用PHP程序编写，能更高效的批量处理PHP开发中的文件上传，图片处理、批量添加图片水印等问题，在使用本程序前请详细阅读使用说明！

HTML表单页

<form enctype="multipart/form-data" action="uploadx.php" method="post">
<input name="uploadx[]" type="file">
<input name="uploadx[]" type="file">
<input type="submit" value="上传">
</form>
uploadx.php处理页
require ('./classes/uploadx.class.php');
$uploadx = new uploadx;
$uploadx->save = './temp';
$uploadx->name = 'auto';
$uploadx->mini = '200,200,mini';
$uploadx->mark = './images/logo.png,0,60';
print_r($uploadx->is());

参数说明：

$uploadx->save
上传文件的保存目录
$uploadx->name;
上传文件的命名方式
参数说明
auto=自动随机文件名,
null=原文件名(覆盖),
其他自定义如按时间：date('YmdHis');
$uploadx->mini;
生成缩略图参数
width = 生成缩略图宽度。
height = 生成缩略图高度。
mini = 生成缩略图文件后缀附加名
默认留空不生成缩略图;
$uploadx->mark;
上传图片文件添加水印参数：
水印文件,水印位置,水印透明度

位置参数说明：
0 = 随机;
1 = 左上角;
2 = 顶部居中;
3 = 右上角;
4 = 左居中;
5 = 中部居中;
6 = 右居中;
7 = 左下角;
8 = 底部居中;
9 = 右下角;

$uploadx->is(true);
返回已上传文件的数组
is参数说明：
true = 返回所有上传文件
false = 过滤失败文件
$uploadx->is();
返回数据数组格式说明：
name = 上传后已保存的文件名
mini = 生成缩略图的文件名
mark = 添加水印状态，1表示成功，否则失败
code = 错误代码：0表示上传成功
error = 错误信息：上传错误时提示的错误信息
其中生成缩略图和添加水印功能也可单独使用!

以上是对uploadx2.0 进行简单的介绍，
也欢迎各位能在使用过程中进行改进补充
