RE: what are the different types of hook point in Codeigniter?
The list of hook points is shown below.
It is called much before the system execution. Only benchmark and hook class have been loaded at this point.
It is called immediately prior to your controller being called. At this point all the classes, security checks and routing have been done.
It is called immediately after your controller is started, but before any method call.
It is called immediately after your controller is completely executed.
It is used to send the final page at the end of file execution.
It enables you to call your own function in the output class.
It is called after the final page is sent to the browser at the end of the system execution.
