Add a site id to distinguish different websites

Give you two methods:

1. Each website corresponds to different entry files

Thought: In the tp framework, the entry files for the backend and the frontend are admin.php and index respectively. php, then according to this idea, if there are multiple websites, you can create a new entry file such as index2.php, corresponding to the directory of this website, such as: application/Innde2 directory, and then point the project directory to the root directory index2 when setting the domain name .php will do.

2. Use a unified entry file, determine the domain name in the entry file, that is, index.php, and jump to the corresponding directory according to the different domain names.

I don’t want to say too much about this, it’s very simple. I’ll just post the sample code for you:

// Define the application directory based on the domain name
$server = $_SERVER['SERVER_NAME' ];
if($server == '****.com'){
define('APP_PATH','./Mzhuisu/');
}else{
define(' APP_PATH','./Home/');
}
