PHP XML conversion to each other

It was just yesterday that a similar demand was made ... A few lines of code can be done.

If you use curl to get the XML data
$xml = simplexml_load_string ($data);
$data [' tk '] = Json_decode (Json_encode ($xml), TRUE);

If you get the URL data directly,
$xml = Simplexml_load_file ($data);
$data [' tk '] = Json_decode (Json_encode ($xml), TRUE);

Convert the SimpleXML object to JSON first, and then convert the JSON to an array.

XML and Array transfer
