How does SSL/TLS encryption play a crucial role in securing client-server communication in PHP applications?

SSL/TLS encryption plays a crucial role in securing client-server communication in PHP applications by encrypting the data transmitted between the client and the server, ensuring that sensitive information such as login credentials or personal data is protected from eavesdroppers. This encryption protocol establishes a secure connection between the client and server, preventing unauthorized access to the data being exchanged. 

// Enable SSL/TLS encryption in PHP application
$context = stream_context_create([
    'ssl' => [
        'verify_peer' => true,
        'verify_peer_name' => true
    ]
]);

$url = 'https://example.com/api';
$data = ['username' => 'user', 'password' => 'pass'];

$response = file_get_contents($url, false, $context);
