I have been searching online for the past 2 hours and couldn't find an answer. I have some data stored in my database in JSON format. I want to add a new key and value to the json data. Example

{ "systemService":"1234", "DATA_PLAN":"SMEF", "amount":"5000" } $message = .$name "" .$post; Copy code

I want to add a new key and value to it."message":$message

to something like this.

{ "systemService":"1234", "DATA_PLAN":"SMEF", "amount":"5000" "message":"mike accountance" } Copy code
