_ _, I have achieved good results today. I have completed the three functions of the website, RSS subscription, automatic writing of website map, and routing configuration. Okay, now I will record them one by one.

1. Routing configuration
When no routing is set, the path is like this
[php]
http://www.xiuxiandou.com/content/it/13533/The legendary investor in Silicon Valley talks about the 4 major mistakes that start-up entrepreneurs often make
                                                         
content =>controller,it=>method,13533=>id, the legendary investor in Silicon Valley talks about the 4 major mistakes that start-up entrepreneurs often make=>title
http://www.xiuxiandou.com/content/it/13533/The legendary investor in Silicon Valley talks about the 4 major mistakes that start-up entrepreneurs often make
                                                         
content =>controller,it=>method,13533=>id, Silicon Valley legendary investor talks about the 4 major mistakes that start-up entrepreneurs often make=>title
After setting the routing, the access path is:
[php]
http://www.xiuxiandou.com/content-it-13533-The legendary investor in Silicon Valley talks about the 4 major mistakes that start-up entrepreneurs often make
http://www.xiuxiandou.com/content-it-13533-The legendary investor in Silicon Valley talks about the 4 major mistakes that start-up entrepreneurs often make
Others are similar, the path configuration is
[php]
/*sitemap usage*/
$route['content-(:any)-(:num)'] = "content/$1/$2";
/*Display routing on the front page*/
$route['content-(:any)-(:num)-(:any)'] = "content/$1/$2/$3";
                                                       
/*RSS subscription route*/
$route['feed-rss-(:any)'] = "feed/rss/$1";
/*Blog routing*/
$route['blog-(:num)-(:any)'] = "blog/blogview/$1/$2";
$route['blog-blogtypes-(:any)']="blog/blogtypes/$1";
                                                       
/**message**/
$route['me'] = "indexs/me";
/**template**/
$route["template"]="indexs/template";
/**Today's update**/
$route["indexs-(:any)"]="indexs/$1";
/*sitemap usage*/
$route['content-(:any)-(:num)'] = "content/$1/$2";
/*Display routing on the front page*/
$route['content-(:any)-(:num)-(:any)'] = "content/$1/$2/$3";
                                                       
/*RSS subscription routing*/
$route['feed-rss-(:any)'] = "feed/rss/$1";
/*Blog routing*/
$route['blog-(:num)-(:any)'] = "blog/blogview/$1/$2";
$route['blog-blogtypes-(:any)']="blog/blogtypes/$1";
                                                       
/**message**/
$route['me'] = "indexs/me";
/**template**/
$route["template"]="indexs/template";
/**Today's update**/
$route["indexs-(:any)"]="indexs/$1";
2. RSS
Create the Rss.php file in the libraries directory, which is mainly responsible for generating data content in RSS format
[php]
/** 
 * Rss 
 */
class Rss{
                                                         
public function write_rss($in_datas){
$CI=& get_instance();
$CI->load->helper('xml');
$CI->load->helper('text');
                                                       
$xml_str=""
                    ."";  
            if(!emptyempty($in_datas)){  
                    $xml_str.=""

                                if(!emptyempty($in_datas["xml_datas"])){  
                                    foreach($in_datas["xml_datas"] as $k => $v){

                                        }  
                                    }  
                                }  
                    $xml_str.="";  
                                 
            }  
            $xml_str.="";  
           return $xml_str;  
    }  
}  
 
/**

2、RSS控制类

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

3. Site map
The site map is mainly XML spelled according to the sitemaps.xml protocol. The protocol address: http://www.sitemaps.org/protocol.html

Dependency Injection vs. Service Locator in PHPDependency Injection vs. Service Locator in PHPMay 13, 2025 am 12:10 AM

Select DependencyInjection (DI) for large applications, ServiceLocator is suitable for small projects or prototypes. 1) DI improves the testability and modularity of the code through constructor injection. 2) ServiceLocator obtains services through center registration, which is convenient but may lead to an increase in code coupling.

PHP Dependency Injection: Improve Code TestabilityPHP Dependency Injection: Improve Code TestabilityMay 12, 2025 am 12:03 AM

Dependency injection (DI) significantly improves the testability of PHP code by explicitly transitive dependencies. 1) DI decoupling classes and specific implementations make testing and maintenance more flexible. 2) Among the three types, the constructor injects explicit expression dependencies to keep the state consistent. 3) Use DI containers to manage complex dependencies to improve code quality and development efficiency.
