How can PHP be used to handle HTTP PUT requests effectively and securely?

To handle HTTP PUT requests effectively and securely in PHP, you can use the `file_get_contents('php://input')` function to retrieve the raw input data from the request body. This allows you to access the PUT data directly without relying on PHP superglobals like `$_POST` or `$_REQUEST`, which are not typically populated for PUT requests. Additionally, you should validate and sanitize the input data to prevent any potential security vulnerabilities. 

// Retrieve raw input data from the PUT request
$input_data = file_get_contents('php://input');

// Validate and sanitize the input data as needed
// Example: sanitize the input data using htmlspecialchars
$sanitized_data = htmlspecialchars($input_data);

// Process the input data further as needed
// Example: save the data to a file
file_put_contents('put_data.txt', $sanitized_data);
