How can PHP developers ensure that Range requests are processed correctly and securely?

To ensure that Range requests are processed correctly and securely in PHP, developers can check the Range header in the incoming request and validate the range values before serving the requested content. This helps prevent potential security risks such as serving unintended data or exposing sensitive information. 

// Check if Range header is present in the request
if(isset($_SERVER['HTTP_RANGE'])) {
    // Validate the range values to prevent security risks
    $range = $_SERVER['HTTP_RANGE'];
    
    // Process the range request accordingly
    // Serve the requested content based on the range values
} else {
    // Handle the request without Range header
    // Serve the full content or return an error message
}
