PHP實現抓取Google IP並自動修改hosts檔案，_PHP教程

PHP實現抓取Google IP並自動修改hosts檔案，

無聊中居然又找到個php版本的抓取google hosts的檔案,試了下還可以用,ping了下ip,延遲也不是很高,網頁開啟測試了下速度也很快,大家有興趣的話可以試試.

自動更新hosts檔案， 不覆蓋已存在的記錄，方便使用,不用每次都 複製->開啟hosts檔案->粘貼。

php檔案:

<?php/** * 免翻牆上google * @author 自娛自樂自逍遙  * 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.
