我的脚本打开两个文件：whITelist.txt和blacklist.txt填充ip地址.

我想在whitelist.txt中将blacklist.txt中所有ip的实例添加到变量中.

此脚本最多可以存储2个通配符.

它现在运行37分钟,我希望这更快.

$blacklist = file_get_contents("blacklist.txt");
$whitelist = file_get_contents("whitelist.txt");

$black_ips = explode("\n",$blacklist);
$white_ips = explode("\n",$whitelist);

$wildcard = array();
for($i = 0; $i < 256; $i++) {
  $wildcard[] = $i;
}

foreach($black_ips as $bkey => $black) {
  if(stristr($black,".")) {

    foreach ($white_ips as $wkey => $white) {
      $count = substr_count($white,'*');

      if($count) {
        switch($count){
          case 1:
            foreach ($wildcard as $i) {
              if(substr($white,strlen($white) - 1) . $i == $black){
                continue 4;
              }
            }
            break;
          case 2:
            foreach ($wildcard as $i) {
              foreach ($wildcard as $k) {
                if(substr($white,strlen($white) - 3) . $i . '.' . $k == $black){
                  continue 5;
                }
              }
            }
            break;
        }
      }
      else if($black == $white) {
        continue 2;
      }
    }
    $Nginxdeny .= "deny " . $black . ";\n";
  }
}

$white = array(
    '192.168.*.*','10.10.10.*',);

$black = array(
    '192.168.8.8','10.10.10.3','10.10.1.2',);

$patterns = array();
foreach ($white as $subnetwork) {
    $patterns[] = str_replace(array('.','*'),array('\\.','(\d{1,3})'),$subnetwork);
}

$notMatched = array();
foreach ($black as $ip) {
    foreach ($patterns as $pattern) {
        if (PReg_match("/^{$pattern}$/",$ip)) {
            continue 2;
        }
    }
    $notMatched[] = $ip;
}

var_dump($notMatched);

array(1) {
  [0]=>
  string(9) "10.10.1.2"
}
