покрытие XML для Json PHP

Question

Я пытаюсь конвертировать XML в JSON без использования json_encode. Я написал ниже PHP-код для его преобразования, но он не работает должным образом. Название для данных показывает, но не сами данные. Abit трудно объяснить, но, пожалуйста, запустите его сами, и вы поймете, что я имею в виду.

Это задача для потенциальной работы, и они сказали не использовать json_encode. Это часть процесса собеседования. Ниже мой код:

Answer 1

Вы можете попробовать этот метод:

//xml->array:
$arr=base64_encode(array('note'=>'Tove','from'=>'Jani')); //head........
$json_arr='{"arr":"'.$arr.'"}'; //json
$ARR=json_decode($json_arr,1); //array
$Bascode=base64_decode($ARR['arr']);  //base64_decode value
