024.CI4框架CodeIgniter辅助函数类之：URL辅助函数

Posted 2020-11-28 像一棵海草海草海草

01. php的CI4框架自带了很多好用的URL辅助函数，我选择了以下这些比较常用的列了出来，代码如下：

<?php namespace App\\Controllers;

// http://127.0.0.1/CI4/public/index.php/hello/
class Hello extends BaseController
{
    public function index()
    {
        //http://localhost/CI4/index.php/news/local/123 0
        echo site_url(\'news/local/123\') . \' 0<br>\';
        //http://localhost/CI4/index.php/news/local/123 1
        $segments = array(\'news\', \'local\', \'123\');
        echo site_url($segments) . \' 1<br>\';
        //http://localhost/CI4 2
        echo base_url() . \' 2<br>\';
        //http://localhost/CI4/blog/post/123 3
        echo base_url("blog/post/123") . \' 3<br>\';
        //http://localhost/CI4/images/icons/edit.png 4
        echo base_url("images/icons/edit.png") . \' 4<br>\';
        //hello 5
        echo uri_string() . \' 5<br>\';
        //http://localhost/CI4/hello 6
        echo base_url(uri_string()) . \' 6<br>\';
        //hello 7
        echo uri_string(\'http://some-site.com/blog/comments/123\') . \' 7<br>\';
        //index.php 8
        echo index_page() . \' 8<br>\';
        //My News 9
        echo anchor(\'news/local/123\', \'My News\', \'title="News title"\') . \' 9<br>\';
        //My News 10
        echo anchor(\'news/local/123\', \'My News\', array(\'title\' => \'The best news!\')) . \' 10<br>\';
        //Click here 11
        echo anchor(\'\', \'Click here\') . \' 11<br>\';
    }
}
