代码如下:

function write_naps_bot(){
$useragent=get_naps_bot();
// echoExit($useragent);
if ($useragent=="false") return FALSE ;
date_default_timezone_set("Asia/Shanghai");
$date=date("Y-m-d H:i:s");
$ip=$_SERVER[REMOTE_ADDR];
$url="http://".$_SERVER[HTTP_HOST].$_SERVER[REQUEST_URI];
// echoExit($url);转载注明www.chhua.com
if (!file_exists("./log/bot.html")){
$botfile=fopen("./log/bot.html", "w");
$fileHeader="<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>访问查看</title>
</head>
<a href="../?action=delbot">删除日志</a><hr>
";
// echoExit($botfile);转载注明www.chhua.com

fputs($botfile, $fileHeader);
fclose($botfile);
}else
{ $filesize=filesize("./log/bot.html");
if ($filesize>=100000){
$botfile=fopen("./log/bot.html", "w");
$fileHeader="<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>访问查看</title>
</head>
<a href="../?action=delbot">删除日志</a><hr>
";
fputs($botfile, $fileHeader);
fclose($botfile);
}else {
$botfile=fopen("./log/bot.html", "a+");
}

//$size="当前文件大小为：".$filesize." ";转载注明www.chhua.com

$useragent="USER:".$useragent." ";
$date="TIME:".$date." ";
$ip="IP:".$ip." ";
$url="URL：<a href='$url' target='_blank'>".$url."</a> ";
$fileStr=$useragent.$date.$ip.$url;
fputs($botfile, $fileStr);
fclose($botfile);
}
}

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){

}

}
