What is the issue with storing SimpleXMLElement objects in a multidimensional array in PHP?

Storing SimpleXMLElement objects in a multidimensional array in PHP can lead to unexpected behavior because SimpleXMLElement objects are not standard PHP objects and can behave differently than expected when stored in arrays. To solve this issue, you can convert the SimpleXMLElement objects to arrays before storing them in the multidimensional array. 

// Convert SimpleXMLElement object to array before storing in multidimensional array
$xml = simplexml_load_string($xmlString);
$array = json_decode(json_encode($xml), true);

$multiArray = [
    'key1' => [
        'subkey1' => $array
    ]
];

// Access the stored SimpleXMLElement data
echo $multiArray['key1']['subkey1']['element1'];
