What are some best practices for transferring data between web servers using PHP?

When transferring data between web servers using PHP, it is important to ensure the data is securely transmitted and received. One best practice is to use HTTPS for secure communication. Additionally, consider using authentication methods such as API keys or OAuth to verify the identity of the servers involved in the data transfer. 

// Example code snippet for transferring data between web servers using PHP with cURL
$url = 'https://example.com/api/endpoint';
$data = array('key1' => 'value1', 'key2' => 'value2');

$ch = curl_init($url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);

$response = curl_exec($ch);

if($response === false){
    echo 'Error: ' . curl_error($ch);
} else {
    echo 'Data transferred successfully: ' . $response;
}

curl_close($ch);
