php实现屏蔽掉黑帽SEO的搜索关键字

 我给大家一个方法 我的思路

思路就是这样的 那些大佬们想做这个东西大部分还是要留QQ或者电话号码

那么我就匹配里面的规则 找出搜索里面的数字 然后判断数字字符串的长度 进而去判断 是否为垃圾搜索

奉上代码:

1

2

3

4

5

6

7

8

9

10

11

12

13

14

15

16

17

18

19

20

21

22

23

function findNum($str=''){ //取出字符串里面的所有数字

$str=trim($str);

if(empty($str)){return '';}

$result='';

for($i=0;$i

if(is_numeric($str[$i])){

$result.=$str[$i];

}

}

return $result;

}

$the_lnum=strlen(findNum($q));//获取数字字符串长度

if($the_lnum>6){ //判断长度是否超过6 超过则直接301到搜索页面

header("HTTP/1.1 301 Moved Permanently");

header("Location: http://".$_SERVER['HTTP_HOST']."/search.php");

exit();

}
