How to queue API requests in PHP?

Question

PHP

I have a number of php scripts that connect as clients to a REST API of a third party service. All scripts use the same login/password for authentication. The problem is that the API server only accepts one connection at a time. Accordingly, if several scripts try to connect to the API server at the same time, they receive an error.
How can I organize a request queue? I thought about creating a database entry or a lock file when opening a connection to the service and removing it when the connection ends, but this does not solve the issue of request ordering.

Answer 1

Why does the database not solve the question of precedence? Recorded in the database scripts in the startup order. Then write a script that checks if there are records for execution in the database, if there are, it takes the record and runs the corresponding script, setting a flag in the database, for example, is_executed, to true. And by cron you can run this script every minute.
