将自定义配置文件加载到Codeigniter库中 [英] Loading custom config file into a Codeigniter library

问题描述

我知道这可能很简单，但我没有。我已经创建了一个库，并且想从配置文件中加载参数。因此，这是我所拥有的示例：

I know this is probably simple, but I'm not getting. I've created a library, and I want to load the parameters from a config file. So here's an example of what I have:

// libraries/Mylib.php
class Mylib {
   var $ci;
   var $key;
   public function _construct {
     $this->ci =& get_instance();
     $this->ci->config->load('mylib');
     $this->key = $this->ci->config->item('key');
   }
   public function myKey() {
     return "Key=" . $this->key;
   }
}

// config/mylib.php
$config['key'] = 'randomcharacters';

我加载了库，并尝试打印出myKey函数，但它只返回 Key = ，没有实际的密钥。我缺少什么？

I load the library, and try to print out the myKey function, but it just returns "Key=", without the actual key. What am I missing?

推荐答案

似乎您错过了构造函数的下划线：

It seems like you missed an underscore for your constructor:

而不是

public function _construct () {

您应该使用

public function __construct () {
