mixed calculate
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 48-1. Calculating broadcast and network address
<?php require 'Net/IPv4.php'; // create IPv4 object $ip_calc = new Net_IPv4(); // set variables $ip_calc->ip = "192.168.1.10"; $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(); } ?>
boolean - Returns TRUE on success, PEAR_Error on failure.
