SEO : Search Engine Spider catcher

To check what types of the Spiders reach your website and their frequencies, you can use the php code to know the Spiders' movement built by 黑色梦中 from bloghuman.

The php code is as the followings:

function get_naps_bot()
{
$useragent = strtolower($_SERVER['HTTP_USER_AGENT']);

if (strpos($useragent, 'googlebot') !== false){
return 'Googlebot';
}

if (strpos($useragent, 'msnbot') !== false){
return 'MSNbot';
}

if (strpos($useragent, 'slurp') !== false){
return 'Yahoobot';
}

if (strpos($useragent, 'baiduspider') !== false){
return 'Baiduspider';
}

if (strpos($useragent, 'sohu-search') !== false){
return 'Sohubot';
}

if (strpos($useragent, 'lycos') !== false){
return 'Lycos';
}

if (strpos($useragent, 'robozilla') !== false){
return 'Robozilla';
}
return false;
}


function nowtime(){
$date=date("Y-m-d.G:i:s");
return $date;
}

$searchbot = get_naps_bot();

if ($searchbot) {
$tlc_thispage = addslashes($_SERVER['HTTP_USER_AGENT']);
$url=$_SERVER['HTTP_REFERER'];
$file="robotlog.txt";
$time=nowtime();
$data=fopen($file,"a");
fwrite($data,"Time:$time robot:$searchbot URL:$tlc_thispage\n");
fclose($data);
}
