What a robot!

Define (' Isrobot ', Getrobot ()), if (Defined (' Norobot ') && Isrobot) {Exit (header ("http/1.1 403 Forbidden");}

The above code, said to be to prevent the robot access, I do not understand where the representative is the machine person?

Judging the function of the robot is so written, what's the mystery?

function Getrobot () {if (!defined (' Is_robot ')) {$kw _spiders = ' bot| crawl| Spider|slurp|sohu-search|lycos|robozilla '; $kw _browsers = ' msie| netscape| opera| konqueror| Mozilla '; if (Preg_match ("/($kw _browsers)/", $_server[' Http_user_agent ')) {define (' Is_robot ', FALSE);} elseif (Preg_ Match ("/($kw _spiders)/", $_server[' Http_user_agent ')) {define (' Is_robot ', TRUE);} else {define (' Is_robot ', FALSE);}} return Is_robot;}

The other few do not know, but this can only prevent normal crawling, people who forged or not can not prevent

Isn't there a good one to run?

$kw _spiders = ' bot| crawl| Spider|slurp|sohu-search|lycos|robozilla '; What do you mean?

Bot| crawl| Spider|slurp|sohu-search|lycos|robozilla
It's a regular pattern to match.
Bot,spider ... Is a spider's logo, the general search engine will write
