The difference between single-threaded and multi-threaded php

What is multi-threading?

Multi-threading means that a program contains multiple execution streams, that is, multiple different threads can be run simultaneously in one program to perform different tasks, which means that a single program is allowed to create multiple parallel Execution threads to complete their respective tasks.

Benefits of multi-threading:

Can improve CPU utilization. In a multi-threaded program, when one thread must wait, the CPU can run other threads instead of waiting, which greatly improves the efficiency of the program.

Single-threaded:

Single-threaded means that when the program is executed, the program paths (processed things) run are sequential and must be processed in the previous step. Okay, the rest will be executed later.

The difference between multi-threading and single-threading:

For example, when you go to work in the morning and are about to clock in, your phone rings. . If you answer the phone first, wait until you finish answering, and check in, it is a single thread.

If you answer the phone with one hand and clock in with the other. It's multi-threading. The result of both things is the same, you answered the phone and punched the card.
