what is php routing

What is the routing mechanism of PHP

1. The routing mechanism is to convert a specific form of The parameters corresponding to the system are extracted from the URL structure. (Recommended learning: PHP video tutorial)

For example, such as: http://main.test.com/article/1; among them: /article/1 -> ? _m=article&id=1.

2. Then convert the URL with corresponding parameters into a specific form of URL structure, which is the reverse process of the above process.

PHP’s URL routing method

In general: Get path information->Process path information

URL routing method:

The first is mapping through url parameters, usually two parameters, representing the controller class and method such as index.php?c=index&m=index What is mapped to is the index method of the index controller.

The second method is through url-rewrite. The advantage of this is that it can map other suffixes that do not end in php. Of course, the first method can also be achieved through rewrite. , but it is also common to use rewrite purely. Generally, you need to configure the

rewrite rules of apache or nginx

<IfModule mod_rewrite.c>  
    RewriteEngine On  
    RewriteBase /  
    RewriteRule ^index\.php$ - [L]  
    RewriteCond %{REQUEST_FILENAME} !-f  
    RewriteCond %{REQUEST_FILENAME} !-d  
    RewriteRule . /index.php [L]  
</IfModule>
Copy after login

The third is to pass The pathinfo method, the so-called pathinfo, is a URL that looks like this.

xxx.com/index.php/c/index/aa/cc, when apache processes this URL, it will input the part after index.php into the environment variable $_SERVER['PATH_INFO'], which Equal to /c/index/aa/cc.

Then our router can analyze this string by parsing it. Where the following parts are put into the parameters will vary according to each framework.
