Are there any specific PHP functions or methods that should be used when querying a Shoutcast server to avoid displaying irrelevant characters?

When querying a Shoutcast server using PHP, it is important to use the appropriate functions to handle the response data. One common issue is that the response may contain irrelevant characters such as null bytes or control characters, which can affect the display of the data. To avoid displaying these irrelevant characters, you can use functions like `preg_replace` or `filter_var` to sanitize the response before displaying it. 

// Query the Shoutcast server and get the response
$response = file_get_contents('http://your-shoutcast-server.com/stats');

// Sanitize the response to remove irrelevant characters
$sanitized_response = preg_replace('/[^\x20-\x7E]/', '', $response);

// Display the sanitized response
echo $sanitized_response;
