用geo查IP这个。。粉简单。。

Posted by Albert in PHP语言学习 on April 29th, 2009

inc文件在这里http://geolite.maxmind.com/download/geoip/api/php/geoip.inc 应该留着这个能更新一下
更精确的在 http://geolite.maxmind.com/download/geoip/api/php/geoipcity.inc
数据文件在

http://geolite.maxmind.com/download/geoip/database/GeoLiteCountry/GeoIP.dat.gz

  1. #!/usr/bin/php -q
  2. <?php
  3. // This code demonstrates how to lookup the country by IP Address
  4. include("geoip.inc");
  5. // Uncomment if querying against GeoIP/Lite City.
  6. // include("geoipcity.inc");
  7. $gi = geoip_open("/usr/local/share/GeoIP/GeoIPCity.dat",GEOIP_STANDARD);
  8. echo geoip_country_code_by_addr($gi, "24.24.24.24") . "\t" .

使用php的curl类，检测socket5代理服务器可用性

Posted by Albert in PHP语言学习 on April 27th, 2009

设计初衷当然是用php curl bind不一个sokcet5去访问一个随机页面（公网）这个页面的功能就是通过一个md5来验证sokcet5服务器是否真的可用
A服务器通过 socket5发出http://xxxx/a.php?t=randkey
B服务器，echo md5($_GET['t'] . mykey);
A服务器拿到content以后也用相同算法算一个$resut看看是不是等于B服务器的echo值，如果一样，就是success 不一样就是failed

通过IP反查相同IP域名的功能

Posted by Albert in PHP语言学习 on April 22nd, 2009

排名第一的当然是http://www.myipneighbors.com/不过近期升级遇到了麻烦停止服务2个多月了,但是它的站长并没有放弃,正在努力寻求解决中.

排名第二的ip地址反查域名网站我给了国内的http://ip.wen.la/不为别的就因为它的信息全,同一IP在国内的反查域名网站中它查出来的域名最多.不过网站速度有待改进.

排名第三的我给了http://www.ip-domain.com.cn/这个网站全体仿制了排名第一的http://www.myipneighbors.com/不过在排名第一的网站暂时无法提供服务的情况这个山寨版的IP反查域名网站无疑是我们最佳选择.(也是国人办的网站山寨无处不在)

排名第四的http://domainbyip.com/是国外IP反查域名的佼佼者,速度也不错,如果我不是中国人的话我会把它排在第二位.

排名第五的http://whosonmyserver.com/不得不承认这个网站查出来的同服务器域名是最多的但是速度也是最慢的一个如果抛弃速度而言的话这是个不可多得反查域名网站,期待着尽快解决速度问题.

排名第六的http://www.robtex.com/是一个提供服务很全的反查网站可以反查dns a记录 mx记录等这里不做详细介绍了因为查出来的内容对于绝大部分的人没有什么用处.

排名第七的http://www.114best.com/ip/国人比较熟悉但是同一IP查出的站点比较少,数据量还有待加强,不过我相信通过努力会解决的毕竟你的身后有13亿人支持你.

排名第八的http://iy8.net/也是国人做的,数据量比较强大不过和排名第三的http://www.ip-domain.com.cn/有点类似.可能来自同一数据库吧.

获取alax排名的php程序

Posted by Albert in PHP语言学习 on April 21st, 2009

第二个参数是表示排名是上升还是下降中～～

  1. <?php
  2. $GLOBALS[‘HOST’]=parse_url($GLOBALS[‘URL’]);
  3. $body=file_get_contents(‘http://www.alexa.com/siteinfo/’.$GLOBALS[‘HOST’][‘host’]);
  4. preg_match("@<div class=\"data (.*)\">(.*)</a></div>(\r|\n|\s|\t)+<div class=\"label\">Traffic Rank@",$body,$dd);
  5. echo "alax traffic rank {$dd[2]} [{$dd[1]}]";
