What are some best practices for handling special characters like the euro symbol in PHP code?

Special characters like the euro symbol can sometimes cause issues in PHP code due to encoding or character set problems. To handle special characters like the euro symbol correctly, it's important to ensure that the PHP file is saved with the proper character encoding (such as UTF-8) and to use functions like utf8_encode() or htmlentities() to properly encode and decode special characters. 

// Ensure the PHP file is saved with UTF-8 encoding
header('Content-Type: text/html; charset=utf-8');

// Use htmlentities() to encode special characters like the euro symbol
$euroSymbol = '€';
$encodedEuroSymbol = htmlentities($euroSymbol, ENT_QUOTES, 'UTF-8');
echo $encodedEuroSymbol;
