How can I print out the file name when I include the file in the function?-php Tutorial

How can I print out the file name when I include a file in a function? for example, the following execution file is available:

Echo 111111;
Function aa ()
{
Include ('Get _ file_list_search.php ');
Echo 'end of aa () ', PHP_EOL;

}
Aa ();
Get_file_list_search.php is printed on the screen during execution.
Why? Can it not be printed?

It depends on how you wrote get_file_list_search.php.

Focus on get_file_list_search.php.
Only include does not seem to be adequate for analysis
