这篇文章主要介绍了PHP实现抓取Google IP并自动修改hosts文件,本文方法可以实现免翻墙上google,小编亲测可用,需要的朋友可以参考下
无聊中居然又找到个php版本的抓取google hosts的文件,试了下还可以用,ping了下ip,延迟也不是很高,网页打开测试了下速度也很快,大家有兴趣的话可以试试.
自动更新hosts文件， 不覆盖已存在的记录，方便使用,不用每次都 复制->打开hosts文件->粘贴。
php文件:
* Date: 2015/2/6 * Time: 11:42 */ define('START_TAG','#google-hosts-2015'); define('END_TAG','#google-hosts-2015-end'); if(!empty($argv[1])){ $params = array(); parse_str($argv[1], $params); if(isset($params['url'])){ define('GOOGLE_HOST_URL', $params['url']); } if(isset($params['del'])){ define('DELETE_GOOGLE_HOST',true); } } defined('GOOGLE_HOST_URL') || define('GOOGLE_HOST_URL', 'http://www.360kb.com/kb/2_150.html'); if(PHP_OS == 'WINNT'){ define('HOSTS_FILE_PATH', 'C:WindowsSystem32driversetchosts'); }else if(in_array(PHP_OS, array('Linux','Darwin','FreeBSD','OpenBSD','WIN32','Windows','Unix'))){ define('HOSTS_FILE_PATH', '/etc/hosts'); }else{ die('Unsupported system!'.PHP_EOL); } if(!is_writable(HOSTS_FILE_PATH)){ die('Without permission, please use the root user to perform!'.PHP_EOL); } $hosts = file_get_contents(HOSTS_FILE_PATH); $startPos = strpos($hosts, START_TAG); if(!defined('DELETE_GOOGLE_HOST')){ $gs = get_google_hosts(); echo GOOGLE_HOST_URL.PHP_EOL; echo $gs.PHP_EOL; }else{ $gs = ''; echo 'reset hosts'.PHP_EOL; } if($startPos){ $_tmp = substr($hosts, $startPos, strpos($hosts, END_TAG) - $startPos + strlen(END_TAG)); $hosts = str_replace($_tmp,$gs,$hosts); }else{ $hosts.= PHP_EOL.$gs; } $old_file_size = filesize(HOSTS_FILE_PATH); if(file_put_contents(HOSTS_FILE_PATH, $hosts)){ die('success. '.PHP_EOL); }else{ die('fail'.PHP_EOL); } function get_google_hosts(){ $html = file_get_contents(GOOGLE_HOST_URL); $html = strip_tags($html); $startPos = strpos($html, START_TAG); $html = substr($html, $startPos, strpos($html,END_TAG) - $startPos); $html = str_replace(' ',' ',$html); return $html.PHP_EOL.END_TAG; }
