如何将数组添加到php中json的数组中？

// 原始JSON数组
$jsonArray = '{"name": "John", "age": 30, "hobbies": ["reading", "gaming"]}';

// 要添加的数组
$newArray = array("language" => "PHP", "framework" => "Laravel");

// 将原始JSON数组转换为关联数组
$originalArray = json_decode($jsonArray, true);

// 将要添加的数组合并到原始数组中
$originalArray["newData"] = $newArray;

// 将最终的数组转换为JSON格式的字符串
$finalJson = json_encode($originalArray);

echo $finalJson;

{"name":"John","age":30,"hobbies":["reading","gaming"],"newData":{"language":"PHP","framework":"Laravel"}}
