SA will be executed. This allows you to save yourself from predefined global variables. The purpose of creating a separate file is to keep the code clean. So welcome to -init on lines 54-61. A PHP file is required. If you use common tools, you only need to include the welcome folder. For safe operation, it is recommended to use the file_exists() function to check whether the included file actually exists. An initialization file (welcome init.php) is created to initialize the welcome page. Add and delete temporary items, welcome logic. A PHP file is required. Let’s look at the code. The
