php实现首页链接查询友情链接检查的代码

网站首页超链接反查友情链接查询外链查询对于其中的思路

复制代码代码如下:

<?php

/*if($_GET['action']=="check"){

$d o ma i n=$_P OST['d o ma i n'];

//域名表单项为空,则获取地址栏参数if($domain==""){

$d o ma i n=$_G ET['d o ma i n'];

}

//网址

$url="http://".$domai n;

//读取网页,返回网页源文件内容function read_url ($str){

$fi le=fopen($str,"r") or die($str. '->远程网址读取失败! <a href="?next=' .($_GET['next']+1). '&action=check&domai n=' .$_GET['domai n']. '">点击继续查询</a><br>');whi le( !feof($fi le)){

$result.=fgets($fi l e,9999);

}fcl os e($fi l e);return $result;

}

//打开sessionsession_start();

//如果$_SESSION['matches']没有赋值就设置它;if( !isset($_SESSION['matches'])){

$result=read_url ($url );preg_match_al l ('/<a(.*?)href="(http:\/\/.*?)"(.*?)>(.*?)<\/a>/i ',$result,$matches);$num=count($matches[2]);fo r($i=0;$i<$n u m;$i++){i f(s tr pos($ma tch es[2] [$i ],$d o ma i n)>0){u ns et($ma tc h es[2] [$i ]);

}

}

$_SESSION['matches']=$matches[2];

}

//直接从session中取出包含网址数组;

$matches[2]=$_SESSION['matches'];

$n=co u nt($ma tc h es[2]);

$next=0;

$next+=$_GET['next'];

$result=read_url ($matches[2] [$next]);if(strpos($result,$domai n)>0){

$value=$matches[2] [$next]. ' <font color=green>true</font><br>';

}else{

$value=$matches[2] [$next]. ' <font color=red>false</font><br>';

}

$values=$_COOKIE['check_result'].$value;setcookie("check_result",$www.hunanwang.net,time()+3600);echo $values;if($next==$n){echo "扫描结束!";

}else{echo '<meta www.visa158.com="refresh" content="1;URL=?next=' .($next+1). '&action=check&domain=' .$d o ma i n. '" />';

}

}else{

//删除coo ki essetcookie("check_result","",ti me()-3600);echo '<form name="form1"method="post" action="?action=check"><input type="text" name="domain">

<input type="submit" name="Submit" value="提交">

<font color="red">*</font>输入域名如:jb51.net

</fo r m>';

}
