Tools to calculate network subnet, prefix, mask, IP range in PHP

Network calculator in PHP

, _(*1)

During searching for good network calculator I couldn't find a good one written in PHP. That's why I've decided to write it using only bitmask operations and math., _(*2)

What can I calculate?

• Network address
• Broadcast address
• CIDR prefix
• First and last IP in the network
• Number of possible hosts in the network

How to use?

$networkCalculator = new NetworkCalculator("192.168.1.14, "255.255.255.0");

echo $networkCalculator->calculateNetworkAddress(); // 192.168.1.0
echo $networkCalculator->calculateBroadcastIp(); // 192.168.1.255
echo $networkCalculator->calculateNetworkMaskLength(); // 24

list($first, $last) = $networkCalculator->calculateIpRange();

echo $first; // 192.168.1.1
echo $last; // 192.168.1.254

echo $networkCalculator; // will print all the information in pretty way
