codeigniter自定义库的常用函数

Question

I need to create custom libraries for my Codeigniter 3 application that have common functions used by all my custom library.

How to use function only in one place?

Answer 1

You can create new custom libraries. The library classes created by you should be placed in your application/libraries folder.

Classes should have basic prototype like this (here the name Myclass as an example):

 <?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');

class Myclass {

    public function my_function()
    {
    }
}

/* End of file Myclass.php */

From within any of your Controller functions you can initialize your class using the standard:

$this->load->library('myclass');

$this->myclass->my_function(); // Object instances will always be lower case
