PHP implementation to obtain Baidu inclusion and snapshot code_PHP tutorial

This article introduces the use of PHP to obtain Baidu's snapshots and included codes. Let's take a look at what kind of functions and encoding conversion functions are used in PHP in this example.

Let’s take a look at the effect code as follows

The code is as follows

代码如下

复制代码

$domain = "www.hzhuti.com";  /*欲查询的域名*/     $site_url = 'http://www.baidu.com/s?wd=site%3A';     $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/";     $gb2312_pattern = iconv("UTF-8","GB2312",$utf_pattern); /*因为百度为GB2312编码*/     $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.hzhuti.com的网页置入$s0字符串中*/     $s1 = @file_get_contents($today);     preg_match($gb2312_pattern,$s0,$all_num); /*匹配"找到相关结果数*个"*/     preg_match($gb2312_pattern,$s1,$today_num);     preg_match($kz_pattern,$s0,$temp);     preg_match($times,$temp[0],$screenshot);     if($all_num[1] == "")         $all_num[1] = 0;     if($today_num[1] == "")         $today_num[1] = 0;     if($screenshot[0] == "")         $screenshot[0] = "暂无快照"; ?>                 百度收录：     百度今日收录：     百度快照日期：

Copy code

$domain = "www.hzhuti.com"; /*Domain name to be queried*/
$site_url = 'http://www.baidu.com/s?wd=site%3A';
$all = $site_url.$domain; /*All URLs included in the domain name*/
$today = $all.'&lm=1'; /*The URL of the domain name included today*/
$utf_pattern = "/Number of related results found (.*)/";
$gb2312_pattern = iconv("UTF-8","GB2312",$utf_pattern); /*Because Baidu encodes GB2312*/
$kz_pattern = "/(.*)/"; /*String used to match snapshot date*/
$times = "/d{4}-d{1,2}-d{1,2}/"; /*Regular expression matching snapshot date, such as: 2011-8-4*/
$s0 = @file_get_contents($all); /*Place the web page of site:www.hzhuti.com into the $s0 string*/
$s1 = @file_get_contents($today);
Preg_match($gb2312_pattern,$s0,$all_num); /*Match "*number of relevant results found"*/
Preg_match($gb2312_pattern,$s1,$today_num);
Preg_match($kz_pattern,$s0,$temp);
Preg_match($times,$temp[0],$screenshot);
If($all_num[1] == "")
          $all_num[1] = 0;
If($today_num[1] == "")
         $today_num[1] = 0;
If($screenshot[0] == "")
         $screenshot[0] = "No snapshot yet";
?>

Baidu included:> ;

Baidu included today: a>

Baidu snapshot date: p>
