README

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';
}

Methods

isValid(mixed $idNumber): bool

Validates the ID number using the Luhn Algorithm and checks if it has a length of 13 digits and is numeric.

isLength13(mixed $idNumber): bool

Checks if the ID number has a length of 13 digits.

isNumber(mixed $idNumber): bool

Checks if the ID number is numeric.

passesLuhnCheck(mixed $idNumber): bool

Validates the ID number using the Luhn Algorithm.

isMale(mixed $idNumber): bool

Determines if the ID number is for a male.

isFemale(mixed $idNumber): bool

Determines if the ID number is for a female.

isSACitizen(mixed $idNumber): bool

Determines if the ID number is for a South African citizen.

isPermanentResident(mixed $idNumber): bool

Determines if the ID number is for a permanent resident.

parse(mixed $idNumber): array

Parses the ID number and returns an array with the following information:

• valid: A boolean indicating if the ID number is valid.
• birthday: The birthdate in the format YYYY/MM/DD.
• age: The age of the individual.
• gender: The gender of the individual (Male or Female).
• citizenship: The citizenship status of the individual (SA Citizen or Permanent Resident).

Use Cases

Validating ID numbers in a registration form

Use the isValid method to validate ID numbers in a registration form to ensure that only valid ID numbers are accepted.

Extracting information from ID numbers

Use the parse method to extract information from ID numbers, such as birthdate, age, gender, and citizenship, to populate user profiles or perform analytics.
