php-whitelist-check
A modern and simple approach to validating IP addresses and domains against a whitelist. It supports both IPv4 and IPv6 addresses and CIDR subnets in addition to domain names and wild-card domains.
Requirements
- PHP 5.3 or newer
Usage
The Check::whitelist()
method takes an array of definitions which will constitute the whitelist. The definitions can either be strings (which will be parsed to their respective objects) or objects.
The Check::check($value)
method is used to check the specified value against the current whitelist. The method will return true if the value matches any of the definitions.
To create your own definition classes just extended Whitelist\Definition\Definition
and implement Whitelist\Definition\IDefinition
Example usage:
require_once("vendor/autoload.php"); $checker = new Whitelist\Check(); try { $checker->whitelist(array( '10.0.3.1', '10.0.0.0/16', '2001:db8:100:934b::3:1', '2001:db8:100:934b::/64', '*.example.com', 'localhost', new Whitelist\Definition\Domain('vpn.work.com'), )); } catch (InvalidArgumentException $e) { // thrown when an invalid definition is encountered } $checker->check('10.0.1.1'); // true $checker->check('10.1.1.1'); // false $checker->check('2001:db8:100:934b::210:2'); // true $checker->check('another.example.com'); // true

This library depends on xrstf/ip-utils
for the IP-related functionality. It also assumes that ip-utils's test cases are sufficient, which is why only trivial testing on these functions have been made for this library.
