PHP代码实现爬虫记录——超管用

实现爬虫记录本文从创建crawler 数据库，robot.php记录来访的爬虫从而将信息插入数据库crawler,然后从数据库中就可以获得所有的爬虫信息。实现代码具体如下：

数据库设计

create table crawler  (   crawler_ID bigint() unsigned not null auto_increment primary key, crawler_category varchar() not null, crawler_date datetime not null default '-- ::', crawler_url varchar() not null, crawler_IP varchar() not null)default charset=utf;

以下文件 robot.php 记录来访的爬虫，并将信息写入数据库：

<?php $ServerName = $_SERVER["SERVER_NAME"] ;  $ServerPort = $_SERVER["SERVER_PORT"] ;  $ScriptName = $_SERVER["SCRIPT_NAME"] ;  $QueryString = $_SERVER["QUERY_STRING"];  $serverip = $_SERVER["REMOTE_ADDR"] ;  $Url="http://".$ServerName; if ($ServerPort != "") {  $Url = $Url.":".$ServerPort ; }  $Url=$Url.$ScriptName; if ($QueryString !="") {  $Url=$Url."?".$QueryString; }   $GetLocationURL=$Url ; $agent = $_SERVER["HTTP_USER_AGENT"];  $agent=strtolower($agent); $Bot =""; if (strpos($agent,"bot")>-) {  $Bot = "Other Crawler"; } if (strpos($agent,"googlebot")>-) {  $Bot = "Google"; }    if (strpos($agent,"mediapartners-google")>-) {  $Bot = "Google Adsense"; } if (strpos($agent,"baiduspider")>-) {  $Bot = "Baidu"; } if (strpos($agent,"sogou spider")>-) {  $Bot = "Sogou"; } if (strpos($agent,"yahoo")>-) {  $Bot = "Yahoo!"; } if (strpos($agent,"msn")>-) {  $Bot = "MSN"; } if (strpos($agent,"ia_archiver")>-) {  $Bot = "Alexa"; } if (strpos($agent,"iaarchiver")>-) {  $Bot = "Alexa"; } if (strpos($agent,"sohu")>-) {  $Bot = "Sohu"; } if (strpos($agent,"sqworm")>-) {  $Bot = "AOL"; } if (strpos($agent,"yodaoBot")>-) {  $Bot = "Yodao"; } if (strpos($agent,"iaskspider")>-) {  $Bot = "Iask"; } require("./dbinfo.php"); date_default_timezone_set('PRC');  $shijian=date("Y-m-d h:i:s", time()); // 连接到 MySQL 服务器 $connection = mysql_connect ($host, $username, $password); if (!$connection) {  die('Not connected : ' . mysql_error()); } // 设置活动的 MySQL 数据库 $db_selected = mysql_select_db($database, $connection); if (!$db_selected) {  die ('Can/'t use db : ' . mysql_error()); } // 向数据库插入数据 $query = "insert into crawler (crawler_category, crawler_date, crawler_url, crawler_IP) values ('$Bot','$shijian','$GetLocationURL','$serverip')"; $result = mysql_query($query); if (!$result) {  die('Invalid query: ' . mysql_error()); }?>

成功了，现在访问数据库即可得知什么时候哪里的蜘蛛爬过你的什么页面。
