How can PHP beginners ensure proper handling of special characters and encoding when extracting data from XML files?

When extracting data from XML files in PHP, beginners should ensure proper handling of special characters and encoding to prevent issues like garbled text or data corruption. This can be achieved by using functions like htmlspecialchars() to encode special characters and utf8_encode() to handle encoding properly. 

$xmlString = '<data><name>José</name></data>';
$xml = simplexml_load_string($xmlString);

$name = $xml->name;
$encodedName = htmlspecialchars($name, ENT_QUOTES, 'UTF-8');
$decodedName = utf8_encode($encodedName);

echo $decodedName; // Output: José
