Hướng dẫn php subnet calculator
Network calculator for subnet mask and other classless (CIDR) network information. FeaturesGiven an IP address and CIDR network size, it calculates the network information and provides all-in-one aggregated reports. Calculations
Provides each data in dotted quads, hexadecimal, and binary formats, as well as array of quads. Aggregated Network Calculation Reports
Standard Interfaces
SetupAdd the library to your { "require": { "markrogoyski/ipv4-subnet-calculator": "4.*" } } Use composer to install the library: $ php composer.phar install Composer will install IPv4 Subnet Calculator inside your vendor folder. Then you can add the following to your .php files to the use library with Autoloading. require_once(__DIR__ . '/vendor/autoload.php'); Alternatively, use composer on the command line to require and install IPv4 SubnetCalculator:
