What are the best practices for securely transferring binary files between client-side jQuery and server-side PHP?

When transferring binary files between client-side jQuery and server-side PHP, it is important to ensure that the data is securely transmitted to prevent any unauthorized access or data breaches. One common practice is to use HTTPS to encrypt the data during transmission. Additionally, it is recommended to validate and sanitize the file data on the server-side to prevent any potential security vulnerabilities. 

// Sample PHP code snippet for securely transferring binary files
if ($_SERVER['REQUEST_METHOD'] === 'POST') {
    $fileData = file_get_contents('php://input');
    
    // Validate and sanitize the file data here
    
    // Save the file to a secure location
    $filePath = '/path/to/save/file';
    file_put_contents($filePath, $fileData);
    
    // Respond with a success message
    echo json_encode(['message' => 'File uploaded successfully']);
} else {
    // Respond with an error message
    http_response_code(405);
    echo json_encode(['error' => 'Method Not Allowed']);
}
