How can I accurately detect the encoding of emails in PHP to ensure proper handling?

When working with emails in PHP, it's important to accurately detect the encoding to ensure proper handling of special characters. One way to do this is by using the mb_detect_encoding() function provided by the Multibyte String extension in PHP. This function can analyze a string and return the most likely encoding based on the byte order mark (BOM) or the character set used. 

// Sample code to detect the encoding of an email body
$emailBody = "Sample email body with special characters é, ü, ñ";

$encoding = mb_detect_encoding($emailBody);

echo "The detected encoding is: " . $encoding;
