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";
}
}
这段代码是否符合您的要求？
$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);
它输出：
array(1) {
[0]=>
string(9) "10.10.1.2"
}
