What is the difference between utf8_encode() and mb_convert_encoding() in PHP?

utf8_encode() is a function in PHP that converts an ISO-8859-1 encoded string to UTF-8. On the other hand, mb_convert_encoding() is a more versatile function that allows you to convert strings between different character encodings, including ISO-8859-1 to UTF-8. If you need more control over the encoding conversion process, it is recommended to use mb_convert_encoding(). 

// Using mb_convert_encoding() to convert ISO-8859-1 to UTF-8
$iso_string = "Hello, world!";
$utf8_string = mb_convert_encoding($iso_string, 'UTF-8', 'ISO-8859-1');
echo $utf8_string;
