How to write cookie parameter from curl?

Question

PHP

Good evening. I can't make sense at all.
I'm trying to make friends with the API for ordering a taxi.
Authorization is a normal request like:
localhost:8080/WebAPI/Login?app=CxTaxiWebAPI&k=***
Where k is the API key
. The response is a JSON object of the form:

"success": true,
"idClient": <Идентификатор клиента (Int64)>, "params": <Параметры системы>, "sessionid": <Идентификатор сессии> }

Further, all work is based on the sessionid stuffed in the cookie.
Expert question: I get this sessionid by sending a curl request. How to cram it into a cookie for half an hour and work with the system?

Answer 1

curl_setopt(ch, CURLOPT_COOKIEFILE, $cookie_file);
curl_setopt(ch, CURLOPT_COOKIEJAR, $cookie_file);
