如何在PHP中循环执行任务并跟踪它[关闭]

I'm developing a web application in PHP in which a user can create tasks for other users to compete.

Those tasks are then stored in MySQL Database.

My question is, How can I cycle through those tasks from the database and present It to the users while keeping track of which tasks that user has completed to avoid presenting the same task to that user. All while also providing the user who created a task with number of users who have completed his/her task.

How can I accomplish this in PHP?

    Well, as far as i can see, i think many - to - many relational tables is what you are looking for, assuming a user can do many tasks and any task can be done by multiple users. You would need 3 tables:

    • Tasks: task_id, task_name, whatever_else_you_need_like_details

    • Users: user_id, w/e

    • Relations: task_id, user_id, status <- the last one is for checking weather a specific task is done by a specific user or in general to see all tasks assigned to a user with their status and vica versa.

    Read up on mano-to-many relations, foreign keys and left/right joins:)
