ipTools

ipTools is a PHP IP number utility toolbox.

"Don't thrust an IP address... ", but sometime you have to deal with them..

Provides IP v4/v6
validation: IP in IP/network(CIDR) ranges
 
and util services:
is valid IP,
expand/compress IP number
IP number to binary and reverse
netmask/cidr etc
...

With courtesy of and inspiration from Paul Gregg <pgregg_at_pgregg_dot_com> and the excellent functions decbin32 and ip_in_range.

Click to get ipTools
from github - at packagist

USAGE

How to check an IPv4/v6 number is valid and in a validity range :

1 - Build a validity range filter
<?php

$validityRange = [
    '192.168.0.1',                // specific match 
    '192.168.0.10-192.168.0.20'   // within a range
    '192.168.1.*                  // with wildcard
    '192.168.2.0/25               // cidr
    '192.168.3.0/255.255.255.128' // or netmask
];

For filters in detail, examine IpTool::isIpNumInRange, below.

2a - 'ad hoc' check
<?php
use Kigkonsult\IpTools\IpTool;

if( ! Iptool::factory( $validityRange )->checkIPnumInRange( $IpNumToTest )) {
    echo 'error message';
}

Iptool::factory( [ filter ] )
filter array|string
throws InvalidArgumentException on invalid filter.
2b - class instance check (with added filter)
<?php
use Kigkonsult\IpTools\IpTool;

$ipValidator = new Iptool( $baseFilterArr );
...
$adHocFilter = '192.168.4.*';
...
if( ! $ipValidator->addFilter( $adHocFilter )
    ->checkIPnumInRange( $IpNumToTest )) {
    echo 'error message';
}

Iptool::__construct( [ filter ] )
filter array|string
throws InvalidArgumentException on invalid filter.
 
IpTool::AddFilter( filter )
filter array|string
throws InvalidArgumentException on invalid filter.
 
IpTool::deleteFilter()
removes filter
 
IpTool::getFilter()
returns (array) filter.
 
(static) METHODS

Here you will find of IPnumber utility methods

IpTool::isValidIP( ipNum )
Return bool true on valid IP (string) v4/v6 number
 
IpTool::expand( ipNum )
Return expanded (string) IPv4 number to 4 octets / full IPv6 number
 
IpTool::isIpNumInRange( ipNum , array acceptRanges [, & matchIx ] )
Return bool true if (valid) (string) IPv4/v6 number match
(any element in array of) IPv4/v6-network filter range(s)
on found, (int) matchIx holds the filter range array index
For filters in detail, examine IpTool::isIpv4InRange and IpTool::isIpv6InRange, below.
 
IpTool::cidr2NetmaskBin( cidr, bitNum )
Return (int) IPv4/v6 CIDR block as binary
bitNum: (int) 32 (IpV4) / 128 (IpV6)
 
IPv4 utility methods
IpTool::isValidIPv4( ipNum )
Return bool true on valid (string) IPv4 number
 
IpTool::IPv42bin( ipNum )
Return (string) IPv4 number as binary
 
IpTool::bin2IPv4( IPbin )
Return binary as IPv4 number
 
IpTool::IpTool::decbin32( dec )
Return binary string (left-)padded to 32 bit numbers
 
IpTool::hasIPv4ValidHost( ipNum )
Return true if hostName exists for a valid (string) IPv4 number and resolves back
 
IpTool::expandIPv4( $ipNum )
Return expanded (string) IPv4 number to 4 octets
 
IpTool::isValidIPv4Cidr( cidr )
Return bool true on valid (int) IPv4 cidr
 
IpTool::ipv4CIDR2Netmask( cidr )
Return (int) IPv4 cidr as netmask
 
IpTool::ipv4Netmask2Cidr( netmask )
Return (string) IPv4 netmask as cidr
 
IpTool::getNetworkFromIpv4Cidr( ipNum, cidr )
Return IPv4 network from (string) IPv4num and (int) cidr
 
IpTool::IPv4Breakout( ipAddress, ipNetmaskCidr [, outputAsIpNum = false ] )
Return array( network, firstIp, lastIP, broadcastIp )
ipAddress string
ipNetmaskCidr = (string) netmask or (int) cidr
outputAsIpNum = false returns binary
outputAsIpNum = true returns (string) Ipv4 numbers
 
IpTool::isIPv4InRange( ipNum , array acceptRanges [, & matchIx ] )
Return true if (valid) (string) IPv4 match any element in array of IPv4/network ranges
on found, (int) matchIx holds the filter range array index
 
IPv4 network filter ranges can be specified as:
example type
'*' Accept all IPs // warning, accepts all
'1.2.3.4' Specific Ipv4
'1.2.3.*' Ipv4 with wildcard
'1.2.3/24' Ipv4 with cidr
'1.2.3.4/255.255.255.0' Ipv4/netmask format
'1.2.3.0-1.2.3.255' Start-End Ipv4 range, note, '-' as separator
 
NOTE, a search for match is done array order !!

ipNum string
on found, (int) matchIx holds the filter range array index
 
IPv6 network filter ranges can be specified as:
example type
'*' Accept all IPs // warning, accepts all
'<IPv6num>' Specific Ipv6
'<IPv6num>/82' Ipv6 with cidr
'<IPv6num>-<IPv6num>' Start-End Ipv6 range, note, '-' as separator
 
NOTE, a search for match is done array order !!
