我是codeigniter的新手,想要在我的第一个扩展另一个库的ci应用程序中添加一个库
class Mylib {}
/application/libraries/Mynewlib.php:
class Mynewlib extends Mylib{}
我在哪里放置Mylib.php以及如何加载Mylib?
谢谢!

在这种情况下,我仍然在寻找最好的实践。
在我的情况下,我有两个类应该从父类扩展。 (付款 - 家长班; Payment_paypal - 与Paypal互动; Payment_nganluong - 与我国内网关Ngan Luong互动 对于每个支付网关,我必须编写一些属性,方法来处理,但几乎基本属性和主题方法是相同的。
我的解决方案:我创建了4个文件:
Payment_base.php
class Payment_base {
// base properties and method
}
Payment.php
require_once (APPPATH.'/libraries/Payment_base.php');
// this is an instance of payment_base,
// when you want to use base method and properties
// just call $payment->...
//
class Payment extends Payment_base {
public function __construct(){
parent::__construct()
}
}
Payment_paypal.php
require_once (APPPATH.'/libraries/Payment_base.php');
class Payment_paypal extends Payment_base{}
//////////////////////////////////////////
require_one 'Payment_base.php';
class Payment_paypal extends Payment_base {
// properties and method
}
4,Payment_nganluong.php
require_once (APPPATH.'/libraries/Payment_base.php');
class Payment_nganluong extends Payment_base {
// properties and method
}
那是它,在控制器中:
$this->load->library('payment');
$this->load->library('payment_paypal');
$this->load->library('payment_nganluong');
$this->payment->myMethod(); // base method
$this->payment_paypal->charge(); // call to paypal to charge money
$this->payment_nganluong->checkout(); // check out with Ngan Luong
// no need to load and use payment_base
希望对你有所帮助。

这适合我。
库文件Mylib.php
class Mylib {
function test()
{
return 1;
}
}
库文件Mynewlib
require_once('Mylib.php');
class Mynewlib extends Mylib{}
控制器
$this->load->library('Mynewlib');
echo $this->Mynewlib->test();

您在application/libraries/mylib.php
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
class MyLib
{
function __construct()
{
// initialize variables if you want
}
public function my_function($something)
{
$out = $something . " World";
return $out;
}
}
/* End of file mylib.php */
然后在您的控制器中,您可以像这样调用您的库
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
class my_controller extends CI_Controller
{
public function index()
{
$this->load->library('mylib'); // call the custom class MyLib
$term = $this->mylib->my_function("Hello");
echo $term; // Hello World
}
}
/* End of file my_controller.php */
/* Location: ./application/controllers/my_controller.php */
希望有所帮助

您可以在库中使用get实例来加载
中的另一个库<?php
class MyLib {
public function __construct() {
$this->CI =& get_instance();
$this->CI->load->library('mylib2');
}
public function something() {
$this->CI->mylib2->some_function();
}
}
