Introduction #

JsonSpread helps to decode json string column and then spread its values into multiple columns. This process is very useful when you want to make calculation bases on the value inside json string.

Example #

use \koolreport\processes\JsonSpread;
class MyReport extends \koolreport\KoolReport
    public function setup()
        ->pipe(new JsonSpread(array(
            "address","jobs" //List of all json-type column name

Code explanation:

  1. In this example, we use JsonSpread process with two columns name input "address" and "jobs". These two columns contain json data in string format.
  2. After being piped though the JsonSpread process, json string will be decoded and spread out to become columns. You will have columns like "addresss.city", "address.country"
