How do I store a JSON Value, with the rejson module in Redis using phpredis on Laravel

Question

Normally when I json_encode and set a value in Redis it gets stored as a string. How do I store a value as JSON

I've tried the following :

$redisCon = Redis::connection('default');

$data = $redisCon->executeRaw(['JSON.new', 'someKeyValue', '{"math":0}']);

but the response keep saying false and the data does not get saved.

I've got RedisJSON support on my redis instance, I'm running the redis/redis-stack-server:latest docker container to check this.

I think redis does not accept json/objects. Just convert your json object to string when saving and back to json when retrieving — Mr. Kenneth

Redis has support for JSON Objects with full-text indexing also redis.io/docs/data-types/json — Abhishek

Ah I solved it :) $data = $redisCon->executeRaw(['JSON.SET', 'someKeyValue', '{"math":0}']); — Abhishek

I manged to solve it, I was using the wrong command JSON.NEW, use JSON.SET instead and also put the path with $.

$data = $redisCon->executeRaw(['JSON.set', 'someKeyValue', '$', '{"math":0}']);
