Extracting Embedded Data from a JSON string was created by Brian Coxon
I'm trying to extract walks of a particular grade but cannot get the correct syntax. Grades are embedded in an array, for example:

["difficulty"]=>
      array(2) {
        ["code"]=>
        string(8) "moderate"
        ["description"]=>
        string(8) "Moderate"

I've tried using this but it returns walks of all grades rather than only Moderate grade walks...

walks-manager.ramblers.org.uk/api/volunt...k&groups=MR&api-key= <>&date=2026-08-27&date_end=2027-08-27&days=&difficulty[description]=Moderate&order=asc

I've also tried ...&difficulty.description=Moderate... and that doesn't work. Is such an extraction possible, and if so what syntax should I be using?
