Installation

composer require ilexn/hkid-check-digit

Upgrade from 4.x to 5.x

The \Ilex\Validation\HkidValidation\Reason\ReasonInterface changed to Enum \Ilex\Validation\HkidValidation\Enum\Reason

//4.x
switch ($hkid->getReason()){
    case \Ilex\Validation\HkidValidation\Reason\ReasonInterface::OK:
        echo('correct');
        echo($hkid->format());
        break;
    case \Ilex\Validation\HkidValidation\Reason\ReasonInterface::PATTEN_ERROR:
        echo('Patten not match');
        break;
    case \Ilex\Validation\HkidValidation\Reason\ReasonInterface::DIGIT_ERROR:
        echo('Digit not match');
        break;
}

//5.x
switch ($hkid->getReason()){
    case \Ilex\Validation\HkidValidation\Enum\Reason::Ok:
        echo('correct');
        echo($hkid->format());
        break;
    case \Ilex\Validation\HkidValidation\Enum\Reason::PattenError:
        echo('Patten not match');
        break;
    case \Ilex\Validation\HkidValidation\Enum\Reason::DigitError:
        echo('Digit not match');
        break;
}

Upgrade from 2.x to 3.x

All the checking now return \Ilex\Validation\HkidValidation\HkId object, not bool

<?php
use Ilex\Validation\HkidValidation\Helper;

require_once 'vendor/autoload.php';
$a = Helper::checkByString($s);
//2.x: $a is bool

//>=3.x
$a->isValid(); //bool
$a->isPattenError(); //bool
$a->isDigitError(); //bool
echo($a->format()); // print the formated HKID.
echo($a->getReason());

//also can get back each parts
echo($a->getPart1());
echo($a->getPart2());
echo($a->getPart3());

Usage example

Quick helper - check by each part

<?php
use Ilex\Validation\HkidValidation\Helper;

require_once 'vendor/autoload.php';

//CA182361(1)
$p1 = 'CA';
$p2 = '182361';
$p3 = '1';

$a = Helper::checkByParts($p1, $p2, $p3);

if ($a->isValid()) {
    echo ('correct');
    echo $a->format(); //CA182361(1)
    echo (string) $a; //CA182361(1)
} else {
    echo ('wrong');
}

Quick helper - check by string

<?php
use Ilex\Validation\HkidValidation\Enum\Reason;use Ilex\Validation\HkidValidation\Helper;

require_once 'vendor/autoload.php';

$s = 'CA182361(1)';

$hkid = Helper::checkByString($s);

switch ($hkid->getReason()){
    case \Ilex\Validation\HkidValidation\Enum\Reason::Ok:
        echo('correct');
        echo($hkid->format());
        break;
    case \Ilex\Validation\HkidValidation\Enum\Reason::PattenError:
        echo('Patten not match');
        break;
    case \Ilex\Validation\HkidValidation\Enum\Reason::DigitError:
        echo('Digit not match');
        break;

Normal

<?php
use Ilex\Validation\HkidValidation\HkidDigitCheck;

require_once 'vendor/autoload.php';

$p1 = 'CA';
$p2 = '182361';
$p3 = '1';
$s = 'CA182361(1)';

$c = new HkidDigitCheck();
$hkid = $c->checkParts($p1,$p2,$p3);
if ($hkid->isValid()) {
    echo ('correct');
    echo $hkid->format();
} else {
    echo ('wrong');
    if ($hkid->isPattenError()) {
        echo('Patten not match');
    }
    if ($hkid->isDigitError()) {
        echo('Digit not match');
    }
}

$hkid = $c->checkString($s);
if ($hkid->isValid()) {
    echo ('correct');
    echo $hkid->format();
} else {
    echo ('wrong');
}
