Execute PHP file in background

Question

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

I need to realise next scheme:

User enter on some page(page 1)
This page starts execution of my large PHP script in background .(Every change is writting to database)
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...

Because this process must go without user's activity

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:

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

Use http requests to the local http server from within your script in combination with phps ignore_client_abort() function.

That way you keep the load inside the http servers worker processes, have a natural limit and queuing of requests comes for free.

I would also remind him to use set_time_limit(0) and register_shutdown_function()
