In what scenarios is it recommended to avoid using mb_detect_encoding in a production environment and instead rely on predefined encoding settings or manual encoding detection methods?

mb_detect_encoding can be unreliable in a production environment as it may not always accurately detect the encoding of a string. It is recommended to use predefined encoding settings or manual encoding detection methods to ensure more consistent results. This can help prevent potential issues with data processing or display due to incorrect encoding detection. 

// Define an array of possible encodings to check
$encodings = ['UTF-8', 'ISO-8859-1', 'Windows-1252'];

// Function to manually detect the encoding of a string
function detect_encoding($string, $encodings) {
    foreach ($encodings as $encoding) {
        if (mb_check_encoding($string, $encoding)) {
            return $encoding;
        }
    }
    return 'Unknown';
}

// Example of how to use the detect_encoding function
$string = "Example string";
$detected_encoding = detect_encoding($string, $encodings);

echo "Detected encoding: " . $detected_encoding;
