解決方法2：or you can Try this library //このソリューションはjsonにprint_rを変換し、かつ確実に動作します。文字列としてlatest_receiptコンテンツを持つように正規表現とstr_replaceを使用して
Try this code snippet here（Copy paste below code and check）
<?php
ini_set('display_errors', 1);
/**
* @author Sahil Gulati <[email protected]>
*/
echo printr_source_to_json(
print_r(
array("Name"=>"Sahil Gulati",

"From"=>array(
"DU"=>array(
"Course"=>"B.Sc. (Hons.) Computer Science.")
)
)
)
, true
)
);
