PHP写的获取各搜索蜘蛛爬行记录代码

那么下面分享一款用php写的获取各搜索蜘蛛爬行记录代码
支持搜索引擎如下
可以记录baidu,google,bing,yahoo,soso,sogou,yodao爬行网站的记录!
php代码如下

<?php
function get_naps_bot()
{
$useragent = strtolower($_server['http_user_agent']);
if (strpos($useragent, 'googlebot') !== false){
return 'google';
}
if (strpos($useragent, 'baiduspider') !== false){
return 'baidu';
}
if (strpos($useragent, 'msnbot') !== false){
return 'bing';
}
if (strpos($useragent, 'slurp') !== false){
return 'yahoo';
}
if (strpos($useragent, 'sosospider') !== false){
return 'soso';
}
if (strpos($useragent, 'sogou spider') !== false){
return 'sogou';
}
if (strpos($useragent, 'yodaobot') !== false){
return 'yodao';
}
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="www.jb51.net.txt";
$time=nowtime();
$data=fopen($file,"a");
fwrite($data,"time:$time robot:$searchbot url:$tlc_thispage\n");
fclose($data);
}
