Fully populates the object properties based on the IP address and netmask/bitmask properties. Once these two fields are populated, calculate() will perform calculations to determine the network and broadcast address of the network.

Example

Example 33-1. Calculating broadcast and network address

<?php  require('Net/IPv4.php');  // create IPv4 object $ip_calc = new Net_IPv4();  // set variables $ip_calc->ip = "a192.168.1.10"; $ip_calc->netmask = "255.255.255.0";  /* alternative method with numerical values: $ip_calc->long = 3232235786; $ip_calc->bitmask = 24; */  // calculate $error = $ip_calc->calculate(); if (!is_object($error)) {   // if returned true, output   echo "Your network address: ".$ip_calc->network."<br />";   echo "Your broadcast address: ".$ip_calc->broadcast."<br />"; } else {   // otherwise handle error   echo "An error occured: ".$error->getMessage(); }  ?>

Return value
