Question

I’ve inherited some code:

include('../cfg/db_setup.php');
require('./fpdf/fpdf.php');

I know that ../cfg means start in the current directory, then go up one level and down into the cfg dir. What does the ./fpdf mean? I’ve never seen a single dot slash used in a file path, and can’t seem to find the fpdf directory anywhere on our server, but the code is working so apparently it’s there somewhere.

Answer 1

. is defined as the current folder.

So, if the PHP script is located at /path/to/script/, then the second statement will look for /path/to/script/fpdf/fpdf.php
