What are some potential methods for transferring data from one PHP-based website to another without requiring direct database access?

When transferring data between PHP-based websites without direct database access, one potential method is to use APIs to exchange information securely. By creating APIs on both websites, you can define endpoints for data retrieval and submission. This allows for controlled and structured communication between the websites without exposing direct database access.

// Example of using cURL to send data from one PHP-based website to another using an API endpoint

// Data to be transferred
$data = array(
    'name' => 'John Doe',
    'email' => 'johndoe@example.com'
);

// API endpoint URL
$api_url = 'https://www.example.com/api/transfer_data.php';

// Initialize cURL session
$ch = curl_init($api_url);

// Set cURL options
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

// Execute cURL session
$response = curl_exec($ch);

// Close cURL session
curl_close($ch);

// Handle API response
if ($response) {
    echo 'Data transferred successfully!';
} else {
    echo 'Failed to transfer data.';
}
