$size=$_FILES["UPLOAD"]["size"];
$name=$_FILES["UPLOAD"]["name"];
$type=$_FILES["UPLOAD"]["type"];
$ext = strtolower(substr(strrchr($name,'.'),1));
$uploadname=date("YmdHis").".".$ext;
echo "File Name: ".$name."<br>";
echo "File Size: ".$size."<br>";
echo "File Type: ".$type."<br>";
echo "Upload Name: ".$uploadname."<br>";
if (move_uploaded_file($_FILES['UPLOAD']['tmp_name'],'./'.$uploadname))
{
    echo 'Upload Ok';
}else
{
    exit("Upload fail");
}

上面是PHP上传文件的一个例子

<form action="upload.php" method="post" enctype="multipart/form-data">
<p>File:
<input type="file" name="UPLOAD" />
<input type="submit" value="Send" />
</p>
</form>

用来给最上面提供本地上传的HTML文件接口
