README

This is a simple helper package that I use when I need to check if an IP is in a given IP range.

All ideas, contributions and criticism are welcome.

Installation

composer require morsvox/ip-range-checker

Usage

Import the class in your script:

use IlkerMutlu\IPRangeChecker\Checker;

$ip = '192.168.0.22';
$checker = Checker::forIp($ip);

Pass the start IP and end IP in an array to the setRange() method.

$checker->setRange([
    '192.168.0.1',
    '192.168.0.28'
]);

// $checker->check() will return true for IPs between
// 192.168.0.1 and 192.168.0.28
// 192.168.0.19 will return TRUE
// 192.168.1.41 will return FALSE

You can also use a wildcard.

$checker->setRange('192.168.0.*');

// $checker->check() will return TRUE for IPs between
// 192.168.0.1 and 192.168.0.255
// 192.168.0.41 will return TRUE
// 192.168.1.41 will return FALSE

OR, you can pass in two IPs separated with a dash.

$checker->setRange('192.168.0.4-192.168.0.54');

// $checker->check() will return TRUE for IPs between
// 192.168.0.4 and 192.168.0.54
// 192.168.0.41 will return TRUE
// 192.168.0.61 will return FALSE

After setting the range, just call the check() method on the checker instance, which will return a boolean value.

$checker->check();

TODO

1. Tests
2. Support dashed IP range strings
3. Support CIDR
