Are there any best practices for handling special characters like "ü" in PHP when processing XML files?
Special characters like "ü" in XML files can cause encoding issues if not handled properly in PHP. To ensure these characters are correctly processed, it is recommended to use functions like `utf8_encode()` or `htmlspecialchars()` when reading or writing XML files. These functions help encode special characters to prevent any encoding errors.
// Read XML file and handle special characters like "ü"
$xmlString = file_get_contents('example.xml');
$xmlString = utf8_encode($xmlString);
// Process XML data
$xml = simplexml_load_string($xmlString);
// Output XML data
echo $xml->asXML();
