Make a task plan, regularly detect which transactions have not been completed, and perform refunds and other operations that have not been executed.

For PHP, the most commonly used method for automatic tasks is cron scheduled execution. Others like guard queues are also possible. In short, a permanent or scheduled processing mechanism is needed.
