Are there any specific PHP functions or techniques that can help prevent query string visibility in URLs?

Query string visibility in URLs can expose sensitive information and potentially lead to security risks. To prevent this, one common technique is to use POST requests instead of GET requests when submitting sensitive data. Additionally, you can encrypt the data before sending it and decrypt it on the server-side to maintain security. 

// Example of encrypting data before sending it in a POST request
$data = [
    'username' => 'john_doe',
    'password' => 'securepassword123'
];

$encryptedData = base64_encode(openssl_encrypt(json_encode($data), 'AES-256-CBC', 'secretkey', 0, 'randomiv'));

// Send encrypted data in a POST request
$response = file_get_contents('https://example.com/api', false, stream_context_create([
    'http' => [
        'method' => 'POST',
        'header' => 'Content-type: application/x-www-form-urlencoded',
        'content' => http_build_query(['data' => $encryptedData])
    ]
]));

// Decrypt the data on the server-side
$decryptedData = openssl_decrypt(base64_decode($_POST['data']), 'AES-256-CBC', 'secretkey', 0, 'randomiv');
$decryptedData = json_decode($decryptedData, true);

// Use the decrypted data as needed
$username = $decryptedData['username'];
$password = $decryptedData['password'];
