How to Validate Aadhaar Card Information using PHP?

Validating Aadhaar card information using PHP is a simple process. It involves the following steps:

Step 1: Obtain Aadhaar card information from the user

The first step is to obtain the Aadhaar card information from the user. This can be done using an HTML form that collects the Aadhaar card number, name, date of birth, and other details.

Step 2: Validate the Aadhaar card number

The Aadhaar card number is a unique 12-digit number assigned to each individual. To validate the Aadhaar card number using PHP, you can use the following regular expression:

$pattern = '/^[2-9]{1}[0-9]{3}\s[0-9]{4}\s[0-9]{4}$/';

This regular expression checks whether the Aadhaar card number is in the correct format, i.e., it starts with a number between 2 and 9, followed by four digits, a space, four digits, and another space, followed by four more digits.

Step 3: Validate the name

The name on the Aadhaar card must match the name of the user. To validate the name using PHP, you can use the following regular expression:

$pattern = '/^[a-zA-Z\s]+$/';

This regular expression checks whether the name contains only alphabets and spaces.

Step 4: Validate the date of birth

The date of birth on the Aadhaar card must match the date of birth of the user. To validate the date of birth using PHP, you can use the following code:

$date_of_birth = '01-01-1990'; // replace with user input $valid_date = date('d-m-Y', strtotime($date_of_birth)); $current_date = date('d-m-Y'); if ($valid_date < $current_date) { // date of birth is valid } else { // date of birth is invalid
