PHP implements grabbing Google IP and automatically modifying the hosts file,

Out of boredom, I actually found a PHP version to grab the google hosts file. I tried it and it still works. I pinged the IP and the delay was not very high. When I opened the web page and tested it, it was also very fast. Everyone is interested. If so, you can try it.

Automatically updates the hosts file without overwriting existing records. It is convenient to use. You don’t have to copy->open the hosts file->paste every time.

php file:

<&#63;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;
}
