South African ID Validator

The South African ID Validator is a PHP class that validates and extracts information from South African ID numbers. It uses the Luhn Algorithm to validate the ID number and provides methods to determine the gender, citizenship, and birthdate of the individual.

Installation

You can install the package via composer:

composer require designbycode/south-african-id-validator

Usage

Instantiation

To use the South African ID Validator, create an instance of the SouthAfricanIdValidator class:

$validator = new SouthAfricanIdValidator();

Validation

To validate an ID number, use the isValid method:

$idNumber = '9404260051081';
if ($validator->isValid($idNumber)) {
    echo 'ID number is valid';
} else {
    echo 'ID number is invalid';
}

Parsing

To extract information from a valid ID number, use the parse method:

$idNumber = '9404260051081';
$parsedData = $validator->parse($idNumber);
print_r($parsedData);

Output:

Array
(
    [valid] => 1
    [birthday] => Arrya(
        'default' => '1978-04-29',
        'iso' => '1978-04-29',
        'american' => '04/29/1978',
        'european' => '04/29/1978',
        'long' => 'April 29, 1978',
    )
    [age] => 28
    [gender] => Male
    [citizenship] => SA Citizen
)

Gender Determination

To determine the gender of the individual, use the isMale or isFemale methods:

$idNumber = '9404260051081';
if ($validator->isMale($idNumber)) {
    echo 'Male';
} else {
    echo 'Female';
}

Citizenship Determination

To determine the citizenship of the individual, use the isSACitizen or isPermanentResident methods:

$idNumber = '9404260051081';
if ($validator->isSACitizen($idNumber)) {
    echo 'SA Citizen';
} else {
    echo 'Permanent Resident';
}
