[RESOLVED] How to access a file in a directory up from the current directory?

Novic

I am trying to access a file in a directory from a file in another directory that is on the same file hierarchy level.

The file using require_once is located at htdocs/websitemain/file.php
The file I want to call is located at htdocs/includesfiles/include.php.

How would I require include.php from within file.php?

I tried this in file.php:

// why does this not work?
require_once '../includesfiles/include.php';

But it doesn't work. Failed to open stream error is given. What should I be doing?

"Failed to open stream" what? That message is usually followed by "No such file or directory". Are you sure the path is correct (check for typos) and that the file exists? Have you considered using an absolute path instead of a relative one?

You might also output the value returned by [man]getcwd/man to ensure that the path is relative from the location you expected.

NogDog

Or consider using absolute paths based on $_SESSION['DOCUMENT_ROOT'].

bradgrafelman

I think you meant $_SERVER['DOCUMENT_ROOT'], but yeah, that's one of the many other ways. 😉

Actually bg, the second line in NogDogs application is

$_SESSION['DOCUMENT_ROOT'] = $_SERVER['DOCUMENT_ROOT'];

Can anyone guess why its the second line? ;-)

Because the 1st line contains:

// let's waste space *AND* do something rather silly and/or nonsensical...

while the zeroth line contains:

<?php session_start(); // zomg I don't know why but everyone tells me this HAS to be the VERY FIRST THING EVER in your PHP script!

C'mon, he's a professional! Everyone knows the 0th line starts out something like this:

/* Copyright 2014 NogDog Enterprises, d.b.a. Google, Inc.

And, of course, I write this in NogDog's honor, with due & copious respect 🙂

This told me my directory so I was able to make it work with this. The file (a class) was being called as an includes in another directory. I didn't know about this function. Thanks.

(Previous post was a response to bradgrafelman on getcwd(). I can't edit my post(??) and forgot to include the quoted text.)

Derokorian

I guess I never thought of he 0th line, since no IDE I've used starts with 0.

Also, glad to hear you figured things out Novic.
