Is it normal include_once self?

Question

I'm a newbie in PHP. I'm analyzing an existing source code and found this.

// this is the some.php itself!!!
<?
include_once("./some.php"); // is this normal?
...
?>

Why would you need that first of all? The code is there only.. — Sougata Bose, Feb 16 '17 at 05:13
we never needed to include same file inside itself , its logically wrong, — Niklesh Raut, Feb 16 '17 at 05:13
May be is should be `..` like this `include_once("../some.php");` to include file from once folder back with same file name, it is possible. — Niklesh Raut, Feb 16 '17 at 05:15

NO.

There is no reason to include current file, itself.

If using include() not include_once(), it raise infinite loop.

The include_once() statement includes and evaluates the specified file during the execution of the script. This is a behavior similar to the include() statement, with the only difference being that if the code from a file has already been included, it will not be included again.

As the name suggests, it will be included just once. There is no reason to do it..

Is it normal include_once self?
