PHP开发案例：用PHP写一个简单的蜘蛛统计代码

发布时间：2023年12月23日

在前面的文章中我们已经学习了怎么来识别蜘蛛（搜素引擎的爬虫），现在我们来运用我们学习到的知识写一个简单的程序。当然你必须在你需要统计的页面引入spider.php，否则是无法统计到的哦！

一、spider.php

<?php
function?spider(){
$spider='0';//首先定义蜘蛛的默认值为0
$user_agent?=?$_SERVER['HTTP_USER_AGENT'];
$user_agent=strtolower($user_agent);
if(strpos($user_agent,'baidu.php')>='1'){$spider='0';
}elseif(strpos($user_agent,'spider_log.php')>='1'){$spider='0';
}elseif(strpos($user_agent,'spider.php')>='1'){$spider='0';
}elseif(strpos($user_agent,'google')>='1'){$spider='谷歌';
}elseif(strpos($user_agent,'bing')>='1'){$spider='必应';
}elseif(strpos($user_agent,'Slurp')>='1'){$spider='雅虎';
}elseif(strpos($user_agent,'ahrefs')>='1'){$spider='国外SEO蜘蛛';
}elseif(strpos($user_agent,'baidu')>='1'){$spider='百度';
}elseif(strpos($user_agent,'sogou')>='1'){$spider='搜狗';
}elseif(strpos($user_agent,'yahoo')>='1'){$spider='雅虎';
}elseif(strpos($user_agent,'search')>='1'){$spider='必应';
}elseif(strpos($user_agent,'yodao')>='1'){$spider='有道';
}elseif(strpos($user_agent,'mediabot')>='1'){$spider='谷歌广告';
}elseif(strpos($user_agent,'soso')>='1'){$spider='360搜搜';
}elseif(strpos($user_agent,'ia_archiver')>='1'){$spider='Alexa';
}elseif(strpos($user_agent,'bot',)>='1'){$spider='其他蜘蛛';
}elseif(strpos($user_agent,'spider')>='1'){$spider='其他蜘蛛';
}elseif(strpos($user_agent,'robot')>='1'){$spider='其他蜘蛛';
}elseif(strpos($user_agent,'spiders')>='1'){$spider='其他蜘蛛';
}
return?$spider;
}
if(spider()!='0'){
$html[0]=$spider;//蜘蛛名称
$html[1]=$_SERVER["REMOTE_ADDR"];//IP
$html[2]=$_SERVER["SERVER_PORT"];//端口
$html[3]=$_SERVER["HTTP_REFERER"];//访问页面,这里的访问页面为什么是上级页面，因为我们实在网页中使用js代码调用本文件的，如果在你网页的PHP中直接引用本程序
//这里$_SERVER["HTTP_REFERER"]需要换为$_SERVER['HTTP_HOST'].$_SERVER['REQUEST_URI']；
$html[4]=date('Y-m-d?H:i:s',time());//爬取时间
$html[5]=$_SERVER["REQUEST_METHOD"];//访问页面的请求方式
$html[6]=$_SERVER["QUERY_STRING"];//query值
$html=$html[0].'|'.$html[1].'|'.$html[2].'|'.$html[3].'|'.$html[4]."<->";
$file=date("Y-m-d",time()).'.txt';
@file_put_contents("$file",$html,?FILE_APPEND);//将蜘蛛爬取信息添加进txt文件保存到本地
}
?>

二、index.php

<?php
$file=date("Y-m-d",time()).'.txt';
@$file?=?file_get_contents("$file");//获得内容?
@$file?=?explode("<->",$file);
$x=count($file)-1;
$page=$_GET['page'];
$nums=50;
$pages=$x/$nums;
$pages=ceil($pages);
if($page==null?or?$page==0?or?$page==1){
$page=1;
$max=$nums-1;
$min=0;
}else{
$max=$page*$nums-1;
$min=($page-1)*$nums;
$uppage=$page-1;
$upurl='<a?href="http://spider.wensha.info/index.php?page='.$uppage.'">上一页</a>';
$nextpage=$page+1;
$nexturl='<a?href="http://spider.wensha.info/index.php?page='.$nextpage.'">下一页</a>';
}
if($page<$pages){
$nextpage=$page+1;
$nexturl='<a?href="http://spider.wensha.info/index.php?page='.$nextpage.'">下一页</a>';????
}
if($page>$pages){
$max=$x-1;??
$uppage=$page-1;
$upurl='<a?href="http://spider.wensha.info/index.php?page='.$uppage.'">上一页</a>';
$nexturl='';
}
if($page=$pages){
$max=$x-1;
$upurl='';
$nexturl='';
}
$b=0;
for($i=$min;$i<=$max;$i++){
$b=$b+1;
$log?=?explode("|",$file[$i]);
$echo=<<<EOT
????????<tr>
????????????<td>
????????????????&emsp;$b?、?$log[0]
????????????</td>
????????????<td>
???????????????&emsp;$log[1]
????????????</td>

????????????</td>
????????????<td>
???????????????&emsp;<a?href="$log[3]"?target="_blank">$log[3]</a>
????????????</td>
????????</tr>
EOT;
$html=$html.$echo;
}
?>
