uploads.php
复制代码 代码如下:
            header("content-type:text/html;charset=utf-8");
            echo "

";
            print_r($_FILES);
            echo "

            $count = count($_FILES['file']['name']);

            for ($i = 0; $i < $count; $i++) {
                $tmpfile = $_FILES['file']['tmp_name'][$i];
                $filefix = array_pop(explode(".", $_FILES['file']['name'][$i]));
                $dstfile = "uploads/files/".time()."_".mt_rand().".".$filefix;

                if (move_uploaded_file($tmpfile, $dstfile)) {
                    echo "";
                } else {
                    echo "";
                }
            }

核心：<1>上传首页中input的name属性是这么设置的。

　　　<2>用while循环上传多文件。
