Nginx php what happens if I set the number of worker to 4 but have five requests coming at the same time?

the first four requests I think nginx will be assigned to those four worker
will the fifth fail?

No, it will wait, and which of the four comprehensive processes will be processed first will come back to deal with this.

if the first four are not finished and the time exceeds the timeout set by nginx, a timeout error will be returned.
