php 读取 sogourank 与 ChinaRank信息

php 读取 sogourank 与 ChinaRank信息

function sogouRank($domain)
{
 $rank = '';
 $pr = 0;
 $content = get_content('http://www.sogou.com/web?query='.$domain);
 if(preg_match("/</span>([0-9]{1,})</dd>/", $content, $matches))
 {
  $pr = intval($matches[1]);
  $width = ceil(65*$pr/100);
  $rank = '<img src="./images/sg_left.gif" width="2" height="11" /><img src="./images/sg_left_img.gif" width="'.$width.'" height="11" /><img src="./images/sg_right_img.gif" width="'.(65-$width).'" height="11" /><img src="./images/sg_right.gif" width="2" height="11" />';
 }
 $rank = '<a href="http://www.sogou.com/web?query=link%3A'.$domain.'" target="_blank" title="搜狗Rank:'.$pr.'">'.$rank.'</a> '.$pr;
 return $rank;
}

function ChinaRank($domain)
{

 }
 $rank = '<a href="http://www.chinarank.org.cn/detail/Info.do?url='.$domain.'" target="_blank">'.$rank.'</a>';

}

下面来看看在很多程序语言中会使用到的class吧，现在会举个简单的实例来实现php class,类申明,class使用方法哦。

php 读取 alexa信息

function Alexa($domain)

下面来看看根据php读取远程服务文件

function get_content($url)

  curl_setopt($handle, CURLOPT_CONNECTTIMEOUT, 5);
  curl_setopt($handle, CURLOPT_RETURNTRANSFER, 1);
  curl_setopt($handle, CURLOPT_FOLLOWLOCATION, 0);
  $content = curl_exec($handle);
  curl_close($handle);
 }
 elseif(function_exists('fsockopen'))
 {
  $urlinfo = parse_url($url);
  $host = $urlinfo['host'];
  $str = explode($host, $url);
  $uri = $str[1];
  unset($urlinfo, $str);
  $content = '';
  $fp = fsockopen($host, 80, $errno, $errstr, 30);
  if(!$fp)

  else
  {

   fputs($fp, $out);
   while (!feof($fp))

 }
 if(empty($content)) $content = 'Can Not Open Url, Please Check You Server ... <br/>For More Information, Please Visit www.111cn.net;

我们用php来实现数据保存哦，看看吧，过滤一些不合法的字符以及各种防止重复发内容的功能

<?php
include_once("inc/connect.php");

$ip = get_real_ip();

   die('submit=false');
  }else{

   }
  }

 function php_sava($str)
 {
  $farr = array(

   "＜\1\2\3＞",           //如果要直接清除不安全的标签，这里可以留空
   "\1\2",
    );
 
   $str = preg_replace( $farr,$tarr,$str);
    return $str;
 }
 
 function stop_outside_post(){
  $ServerName = @$_SERVER['SERVER_NAME'];
  $Sub_from = @$_SERVER["HTTP_REFERER"];
  $Sub_len = strlen($ServerName);
  $Checkfrom = substr($Sub_from,7,$Sub_len);
  if($Checkfrom!= $ServerName){
   die("警告！你正在从外部提交数据或直接访问c.php文件！请立即终止！！");    
  }
 }
 
  function get_real_ip(){
    $ip=false;
    if(!empty($_SERVER["HTTP_CLIENT_IP"])){
     $ip = $_SERVER["HTTP_CLIENT_IP"];
    }
    if (!empty($_SERVER['HTTP_X_FORWARDED_FOR'])) {
     $ips = explode (", ", $_SERVER['HTTP_X_FORWARDED_FOR']);
     if ($ip) { array_unshift($ips, $ip); $ip = FALSE; }
     for ($i = 0; $i < count($ips); $i++) {
      if (!eregi ("^(10|172.16|192.168).", $ips[$i])) {
       $ip = $ips[$i];
       break;
      }
     }
    }
    return ($ip ? $ip : $_SERVER['REMOTE_ADDR']);
  }
