What is the recommended approach for reading identifiers with a "." in SimpleXML?

When reading identifiers with a "." in SimpleXML, you can access them by using curly braces and quotes around the identifier. This is because SimpleXML treats the "." as a concatenation operator rather than a separator for nested elements. By enclosing the identifier in curly braces and quotes, you can correctly access the desired element. 

$xml = '<data><user.name>John Doe</user.name></data>';
$simplexml = simplexml_load_string($xml);

// Accessing element with a "." in the identifier
$userName = $simplexml->{'user.name'};

echo $userName; // Output: John Doe
