PHP Simple implementation Masking user access to specified IP segments

here to share is a simple use of PHP implementation of the mask specified IP segment code, very practical, the need for small partners can refer to the next.

This period of time in the statistics tool always see some unknown browser, unknown operating system users of the frequent requests and IP are in a paragraph, so I have some questions, these users are valid users. Website access No browser does not have a record of the operating system, I after a few days of analysis to confirm that these visits are not people in the access but some machines or other people in the collection of my station, the idea of a shield of this IP.

The statistics inside the user data without browser record to see the next Shield IP is not realistic IP is more than 100, but carefully watch it is not difficult to see that these IP are concentrated in some IP fault. Think of a way to block the entire IP segment of users, may cause some manslaughter but can ensure that the site traffic is clean.

Okay, I'm not talking nonsense. Below is a description of my implementation of the idea and the implementation of the Code

I was thinking of it. Block IP segment of the front end 111.11.11.11 This IP I'm going to block more access to this IP segment starting with 111.11

My implementation of the idea is to block the IP set to be masked in an array and then use the obtained user's IP to match the array, in the array of the mask is not in the array of the release.

Let's serve. I've written a function that's a rough one, don't squirt.

?

1 2 3 4 5 6 7 8 9 10 11 12 13

/** * 屏蔽IP段 */ function killIp($ip){ $return = false; $ip1 = array('111', '112', '102', '114'); $ip2 = array('1', '2', '3', '4', '5'); $temp = explode('.', $ip); if (in_array($temp[0], $ip1) && in_array($temp[1], $ip2)) { $return = true; } return $return; }
