What are the limitations or pitfalls of using json_encode and json_decode for processing large XML files in PHP?

When processing large XML files in PHP, using json_encode and json_decode can be inefficient and memory-intensive due to the conversion process. To improve performance, it's recommended to use XML parsing libraries like SimpleXML or XMLReader to directly process the XML data without the need for conversion to JSON. 

// Using SimpleXML to process large XML files in PHP
$xml = simplexml_load_file('large_xml_file.xml');
foreach ($xml->children() as $child) {
    // Process XML data here
}
