# **PHP RSA ID Validator**

A professional, lightweight PHP library for validating South African ID numbers. It performs full structural checks, validates birth dates, determines gender, identifies citizenship, and verifies the Luhn check digit. Ideal for forms, authentication systems, HR platforms, and any application requiring reliable South African ID verification.

Features

Validates full RSA ID format (YYMMDDSSSGC A)
Birth date extraction with automatic century detection
Gender identification based on sequence number
Citizen vs resident status
Full Luhn algorithm check digit validation
JSON API support

Installation

Using Composer

composer require phprsa/id-validator

Manual Load

If you’re not using Composer, include the file directly:

require 'vendor/phprsa/id-validator/src/RsaIdValidator.php';

Usage Example

use PhpRsaIdValidator\RsaIdValidator;

$validator = new RsaIdValidator();
$result = $validator->validate('9001014800085');

if ($result['valid']) {
    echo "ID is valid";
} else {
    echo "Error: " . $result['error'];
}

API Endpoint

This project includes a working API endpoint for remote validation.

`id-api.php`

<?php
require __DIR__ . '/vendor/autoload.php';

use PhpRsaIdValidator\RsaIdValidator;

header('Content-Type: application/json');

$data = json_decode(file_get_contents('php://input'), true);
$id   = $data['id'] ?? null;

if (!$id) {
    echo json_encode([
        'success' => false,
        'error'   => 'No ID number supplied'
    ]);
    exit;
}

$validator = new RsaIdValidator();
echo json_encode($validator->validate($id), JSON_PRETTY_PRINT);

Example Request

POST /id-api.php
Content-Type: application/json

{
    "id": "9001014800085"
}

Example Response

{
    "valid": true,
    "id_number": "9001014800085",
    "date_of_birth": "1990-01-01",
    "gender": "Male",
    "citizenship": "SA Citizen",
    "check_digit": 5
}

Browser Test Page (`id.php`)

A small interface for manual validation:

<?php
require __DIR__ . '/vendor/autoload.php';

use PhpRsaIdValidator\RsaIdValidator;

$id       = $_GET['id'] ?? null;
$validator = new RsaIdValidator();
$result    = $id ? $validator->validate($id) : null;
?>

        input { padding: 8px; width: 260px; }
        button { padding: 8px 18px; }
        .box { margin-top: 20px; padding: 15px; border-radius: 6px; }
        .ok { background: #d4edda; }
        .bad { background: #f8d7da; }
    </style>
</head>
<body>

<h2>RSA ID Validator</h2>

<form method="GET">
    <input type="text" name="id" placeholder="Enter ID" value="<?= htmlspecialchars($id) ?>">
    <button type="submit">Check</button>
</form>

<?php if ($result): ?>
<div class="box <?= $result['valid'] ? 'ok' : 'bad' ?>">
    <?php if ($result['valid']): ?>
        <strong>Valid</strong><br><br>
        ID: <?= $result['id_number'] ?><br>
        DOB: <?= $result['date_of_birth'] ?><br>
        Gender: <?= $result['gender'] ?><br>
        Citizenship: <?= $result['citizenship'] ?><br>
        Check Digit: <?= $result['check_digit'] ?><br>
    <?php else: ?>
        <strong>Invalid</strong><br><br>
        <?= $result['error'] ?>
    <?php endif; ?>
</div>
<?php endif; ?>

</body>
</html>

Test Client (`test-api.php`)

<?php

$url = "https://yourdomain.com/id-api.php";

$payload = json_encode(["id" => "9001014800085"]);

$ch = curl_init($url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, ["Content-Type: application/json"]);
curl_setopt($ch, CURLOPT_POSTFIELDS, $payload);

$response = curl_exec($ch);
curl_close($ch);

echo "<pre>";
print_r(json_decode($response, true));
echo "</pre>";
