This example describes the use of CodeIgniter hooks. Share to everyone for your reference, specific as follows:
CodeIgniter executes a box with 7 ellipses in the process diagram, which indicates that 7 hooks were buried during execution. So let's see what the hook is.
Two pieces of text found online:
The full implementation of the hook should be called event-driven. Event-driven is divided into two phases, the first phase is the registration event,

A journey to WCF-the first WCF example (2) and the wcf exampleStep 4: Boarding services through self-boarding
The WCF Service depends on a running process (host). The service host specifies a host for the service. WCF is a message-based communication framework that uses an Endpoint-based communication method.
The endpoint consists of Address, Binding, and Contract ,. Since the three elements should be the first letter ABC, there is an easy-to-remember
C pointer example, C pointer example
In computer science, Pointer is an object in programming languages. With an address, its value directly points to the value in another place in computer memory. Because the address can find the required variable unit, it can be said that the address points to the variable unit. Therefore, what visualizes an address is called a "Pointer ". It means that the memory unit wi
