PHP实现抓取Google IP并自动修改hosts文件

前端技术 2023/09/07 PHP

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:

<?php
/**
 * 免翻墙上google
 * @author 自娱自乐自逍遥 <wapznw@gmail.com>
 * 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;
}
