PHP, Redis, lock produkt, until price increase and after that unlock it

Thank you Itamar,

your answer helps me to find a solution, i used now:

$lock_id = "buy_".$product_id;
if (!$redis->setnx($lock_id, true)) {

this fix the interval between set and read, and it returns only true if it set it successful.

And later on the query worker, i delete it:

$lock_id = "buy_".$product_id;

And it works. For users of AFNetworking or any

Regex to format price
