php代码获取 百度收录和百度快照时间

<?php

    $all = $site_url.$domain; /*域名所有收录的网址*/
    $today = $all.’&lm=1′;    /*域名今日收录的网址*/
    $utf_pattern = “/找到相关结果数(.*)个/”;
    $kz_pattern = “/(.*)/”; /*用以匹配快照日期的字符串*/
    $times = “/\d{4}-\d{1,2}-\d{1,2}/”; /*匹配快照日期的正则表达式，如:2011-8-4*/
    $s0 = @file_get_contents($all);    /*将site:www.ninthday.net的网页置入$s0字符串中*/
    $s1 = @file_get_contents($today);
    preg_match($utf_pattern,$s0,$all_num); /*匹配”找到相关结果数*个”*/
