子网掩码和其他无类（CIDR）网络信息的网络计算器。

功能

给定一个IP地址和CIDR网络大小，它计算网络信息并提供一站式聚合报告。

计算

IP地址
网络大小
子网掩码
网络部分
主机部分
网络中的IP地址数量
网络中的可寻址主机数量
IP地址范围
广播地址
最小和最大主机
所有IP地址
IP地址是否在子网中
IPv4 ARPA域

提供点分十进制、十六进制和二进制格式的每个数据，以及四元组数组。

聚合网络计算报告

关联数组
JSON
字符串
打印到STDOUT

标准接口

JsonSerializable

设置

将库添加到项目中composer.json文件

{
  "require": {
      "markrogoyski/ipv4-subnet-calculator": "4.*"
  }
}

使用 composer 安装库

$ php composer.phar install

Composer将在您的供应商文件夹内安装IPv4 Subnet Calculator。然后您可以将以下内容添加到您的.php文件中，以使用自动加载使用库。

require_once(__DIR__ . '/vendor/autoload.php');

或者，在命令行中使用composer require和安装IPv4 SubnetCalculator

$ php composer.phar require markrogoyski/ipv4-subnet-calculator:4.*

最低要求

PHP 7.2

注意：对于PHP 5.5至7.1，请使用v3.0（markrogoyski/ipv4-subnet-calculator:3.*）

用法

创建新的SubnetCalculator

// For network 192.168.112.203/23
$sub = new IPv4\SubnetCalculator('192.168.112.203', 23);

各种网络信息

$numbeIpAddresses     = $sub->getNumberIPAddresses();      // 512
$numberHosts          = $sub->getNumberAddressableHosts(); // 510
$addressRange         = $sub->getIPAddressRange();         // [192.168.112.0, 192.168.113.255]
$addressableHostRange = $sub->getAddressableHostRange();   // [192.168.112.1, 192.168.113.254]
$networkSize          = $sub->getNetworkSize();            // 23
$broadcastAddress     = $sub->getBroadcastAddress();       // 192.168.113.255

IP地址

$ipAddress        = $sub->getIPAddress();        // 192.168.112.203
$ipAddressQuads   = $sub->getIPAddressQuads();   // [192, 168, 112, 203]
$ipAddressHex     = $sub->getIPAddressHex();     // C0A870CB
$ipAddressBinary  = $sub->getIPAddressBinary();  // 11000000101010000111000011001011
$ipAddressInteger = $sub->getIPAddressInteger(); // 3232264395;

子网掩码

$subnetMask        = $sub->getSubnetMask();        // 255.255.254.0
$subnetMaskQuads   = $sub->getSubnetMaskQuads();   // [255, 255, 254, 0]
$subnetMaskHex     = $sub->getSubnetMaskHex();     // FFFFFE00
$subnetMaskBinary  = $sub->getSubnetMaskBinary();  // 11111111111111111111111000000000
$subnetMaskInteger = $sub->getSubnetMaskInteger(); // 4294966784

网络部分

$network        = $sub->getNetworkPortion();        // 192.168.112.0
$networkQuads   = $sub->getNetworkPortionQuads();   // [192, 168, 112, 0]
$networkHex     = $sub->getNetworkPortionHex();     // C0A87000
$networkBinary  = $sub->getNetworkPortionBinary();  // 11000000101010000111000000000000
$networkInteger = $sub->getNetworkPortionInteger(); // 3232264192

主机部分

$host        = $sub->getHostPortion();        // 0.0.0.203
$hostQuads   = $sub->getHostPortionQuads();   // [0, 0, 0, 203]
$hostHex     = $sub->getHostPortionHex();     // 000000CB
$hostBinary  = $sub->getHostPortionBinary();  // 00000000000000000000000011001011
$hostInteger = $sub->getHostPortionInteger(); // 203

最小和最大主机

$minHost        = $sub->getMinHost();        // 192.168.112.1
$minHostQuads   = $sub->getMinHostQuads();   // [192, 168, 112, 1]
$minHostHex     = $sub->getMinHostHex();     // C0A87001
$minHostBinary  = $sub->getMinHostBinary();  // 11000000101010000111000000000001
$minHostInteger = $sub->getMinHostInteger(); // 3232264193

$maxHost        = $sub->getMaxHost();        // 192.168.113.254
$maxHostQuads   = $sub->getMaxHostQuads();   // [192, 168, 113, 254]
$maxHostHex     = $sub->getMaxHostHex();     // C0A871FE
$maxHostBinary  = $sub->getMaxHostBinary();  // 11000000101010000111000111111110
$maxHostInteger = $sub->getMaxHostInteger(); // 3232264702

所有IP地址

foreach ($sub->getAllIPAddresses() as $ipAddress) {
    echo $ipAddress;
}

foreach ($sub->getAllHostIPAddresses() as $hostAddress) {
    echo $hostAddress;
}

IP地址是否在子网中

$boolTrue  = $sub->isIPAddressInSubnet('192.168.112.5');
$boolFalse = $sub->isIPAddressInSubnet('192.168.111.5');

反向DNS查找（ARPA域）

$ipv4ArpaDomain = $sub->getIPv4ArpaDomain(); // 203.112.168.192.in-addr.arpa
