Block Optimizer

• Arokettu\IP\Tools\BlockOptimizer::optimizeV4(...$blocks)

• Arokettu\IP\Tools\BlockOptimizer::optimizeV6(...$blocks)

Block optimizer allows you to transform a set of IP blocks into an equivalent smaller set by discarding overlapping blocks and gluing adjacent blocks. Example:

<?php

 use Arokettu\IP\IPv4Block;
 use Arokettu\IP\Tools\BlockOptimizer;

 $blocks = [
     // blocks that are contained in the first one
     IPv4Block::fromString('127.0.0.0/8'),
     IPv4Block::fromString('127.0.0.0/16'),
     IPv4Block::fromString('127.0.64.0/24'),
     // adjacent blocks that can be combined
     IPv4Block::fromString('192.168.0.0/24'),
     IPv4Block::fromString('192.168.1.0/24'),
     IPv4Block::fromString('192.168.2.0/23'),
 ];

 $optimized = BlockOptimizer::optimizeV4(...$blocks); // 127.0.0.0/8, 192.168.0.0/22

Compare Helper

• Arokettu\IP\Tools\CompareHelper::compare($left, $right, $strict = false)

• Arokettu\IP\Tools\CompareHelper::strictCompare($left, $right)

• Arokettu\IP\Tools\CompareHelper::nonStrictCompare($left, $right)

Just a wrapper that executes $left->compare($right). A useful shortcut for sorting:

<?php

use Arokettu\IP\Tools\CompareHelper;

$addresses = [/* IP addresses */];
usort($addresses, CompareHelper::nonStrictCompare(...));

// or

$blocks = [/* IP blocks */];
usort($blocks, CompareHelper::nonStrictCompare(...));

• Arokettu\IP\Tools\CompareHelper::sort(&$array, $strict = false)

• Arokettu\IP\Tools\CompareHelper::asort(&$array, $strict = false)

Uses the helper above to call usort or uasort
