How can UTF-8 encoding be utilized to handle Umlaut characters in PHP scripts effectively?

UTF-8 encoding can be utilized in PHP scripts to handle Umlaut characters effectively by ensuring that the PHP file itself is saved with UTF-8 encoding, and by using functions like mb_convert_encoding() or utf8_encode() to convert strings to UTF-8 before working with them.

// Set the encoding of the PHP file to UTF-8
header('Content-Type: text/html; charset=utf-8');

// Convert a string containing Umlaut characters to UTF-8
$string = "Möglichkeiten";
$utf8_string = mb_convert_encoding($string, "UTF-8", "ISO-8859-1");

// Use the UTF-8 encoded string in your PHP script
echo $utf8_string;
