What is the error message "Serialization of 'SimpleXMLElement' is not allowed" in PHP?

The error message "Serialization of 'SimpleXMLElement' is not allowed" occurs when trying to serialize a SimpleXMLElement object directly. To solve this issue, you can convert the SimpleXMLElement object to an array using the `json_encode` and `json_decode` functions. This allows you to serialize the array instead of the SimpleXMLElement object. 

// Create a SimpleXMLElement object
$xmlString = '<data><name>John</name><age>30</age></data>';
$xml = new SimpleXMLElement($xmlString);

// Convert SimpleXMLElement to array
$array = json_decode(json_encode($xml), true);

// Now you can serialize the array
$serializedData = serialize($array);
