超简易服务器端文件查询器
代码如下：
<?php

// 登录
if ($_SERVER[\'PHP_AUTH_USER\'] != \'admin\' || $_SERVER[\'PHP_AUTH_PW\'] != \'123\')
{
    header(\'WWW-Authenticate: Basic realm="用户登录"\');
    header(\'HTTP/1.0 401 Unauthorized\');
    die("未登录");
}

$cur_path = $_GET[\'path\'] ?: dirname(__FILE__);
$cur_path = realpath($cur_path);
if (is_file($cur_path))
{
    header(\'Content-type: text/plain; charset=utf-8\');
    echo file_get_contents($cur_path);
    exit;
}

$pre_path = dirname($cur_path);
$list = glob($cur_path . DS . \'*\');

header(\'Content-type: text/html; charset=utf-8\');
header(\'Cache-Control: no-cache, must-revalidate, max-age=0\');
header(\'Pragma: no-cache\');
