下面来看看WEB页面形式了.

?>

    真正支持单文件和多文件上传类代码，修正了$_FILES[$field]['name']中的$field不能用变量只能和表单中的文件名name="userfile"一致的缺点$_FILES['userfile']['name']，这里<input type="file" name="userfile"> 中的文件名可以随意取。

//index.htm
1、单文件上传
<form method="post" action="./upload.php" name="frmUpload" enctype="multipart/form-data" >
<input type="file" name="userfile" style="WIDTH: 282px">
<input type="submit" align="center" name="upfiles" value="确定"></form>
2、多文件上传
<form method="post" action="./upload.php" name="frmUpload" enctype="multipart/form-data" >
<input type="file" name="userfile[]" style="WIDTH: 282px">
<input type="file" name="userfile[]" style="WIDTH: 282px">
<input type="file" name="userfile[]" style="WIDTH: 282px">
<input type="submit" align="center" name="upfiles" value="确定">
</form>
