在后台执行PHP文件

Question

I have some php code, that execute for a very long time.

I need to realise next scheme:

1. User enter on some page(page 1)
2. This page starts execution of my large PHP script in background .(Every change is writting to database)
3. We sent every N seconds query to database to get current status of execution.

I don't want to use exec command because 1000 users makes 1000 php processes. It's not way for me...

Answer 1

So you basically want a queue (possibly stored in a database) and a command line script ran by cron that process queued items.

Clarification: I'm not sure about what's unclear about my answer, but this complies with the two requirements imposed by the question:

1. The script cannot be aborted by the client
2. You share a single process between 1,000 clients
