How can one determine the codec used in decoding emails in PHP?

To determine the codec used in decoding emails in PHP, you can use the `mb_detect_encoding()` function to detect the character encoding of the email content. This function will return the most likely encoding of the string based on the byte sequence. 

// Get the email content
$emailContent = "Email content here";

// Determine the codec used in decoding the email
$codec = mb_detect_encoding($emailContent);

// Output the detected codec
echo "Codec used: " . $codec;
