PHP pthreads use of multithreaded extensions: a more stable example.

Today, we study the cooperation method of worker stackable, write two kinds of forms, although can work, but will appear the problem of memory not listening to growth;

So the first method of the code message to the author, and now he did not reply to me.

I finally gave up the two-way, directly using the worker, found that now performed 582,000 jobs, the memory does not grow, the speed is basically stable, the code is as follows:
