includes are really messing me up

[D. Alvarado]

Hi,
I have these files

/include/db_info.inc
/html_root/util_fns.inc
/html_root/home_page.php
/html_root/admin/admin_home.php

The page "util_fns.i nc" contains the line

<?php include("../db_info.inc"); ?>

The page home_page.php contains

<?php include("util_f ns.php"); ?>

and admin_home.php contains

<?php include("../util_fns.php"); ?>

but when I visit admin_home, I get the error
"main(../include/db_info.inc): failed to open stream: No such file or
directory". If I change the line in "util_fns.i nc" to:

<?php include("../../db_info.inc"); ?>

the admin_home.php works fine, but the home_page.php page breaks. How
can I write the include line in "util_fns.i nc" to accommodate both
situations?

Thanks, - Dave

What is messing things up is that the directory the file is in is where
the include is oriented from.


To make the orientation the same use $_SERVER['DOCUMENT_ROOT']
as the base part in all the files and the includes too.

Therefore
include($_SERVE R['DOCUMENT_ROOT'] . "../db_info.php");
if the include_path has /include in it.

or

include($_SERVE R['DOCUMENT_ROOT'] . "../include/db_info.php");
if the include_path does not..

Make your include_path setting

include_path /path/to/include/

where /path/to/ is the path to the first of the items you listed.

Then just use

<?php include ('db_info.inc') ; ?>
or better still, use require_once () instead of include ()

The best solution I have found so far is the following code:

function include_once_re lative($path) {
$from = realpath(dirnam e($_SERVER["SCRIPT_FILENAM E"]));
$to = realpath(dirnam e(__FILE__)."/".$path);

include_once(re lative_path($to ,$from));
}

function relative_path ($targetfile, $basedir = '.') {
$basedir = realpath ($basedir);
$targetfile = realpath ($targetfile);

// on windows, check that both paths are on the same drive
if (substr ($basedir, 0, 1) != substr ($targetfile, 0, 1)) {
return false;
}

// split each path into its directories
$base_parts = split ('\/', str_replace ('\\', '/', $basedir));
$target_parts = split ('\/', str_replace ('\\', '/', $targetfile));

// ensure that there are no empty elements at the end (c:\ would cause it)
for ($i = count($base_par ts) - 1; $i >= 0; $i--) {
if ($base_parts[$i] == '') {
unset ($base_parts[$i]);
} else {
break;
}
}
for ($i = count($target_p arts) - 1; $i >= 0; $i--) {
if ($target_parts[$i] == '') {
unset ($target_parts[$i]);
} else {
break;
}
}

// get rid of the common directories at the beginning of the paths
$common_count = 0;
for ($i = 0; $i < count($base_par ts); $i++) {
if ($target_parts[$i] == $base_parts[$i]) {
$common_count++ ;
} else {
break;
}
}
for ($i = 0; $i < $common_count; $i++) {
unset ($base_parts[$i]);
unset ($target_parts[$i]);
}

// build the resulting string
$cnt = count($base_par ts) - 1;
if ($cnt < 1) {
$cnt = 0;
}

return str_repeat ('../', $cnt).implode('/', $target_parts);
}

Stick it into a library file which you /can/ include - and then
you can use:

"include_once_r elative" in place of "include_on ce" - and it takes
account of a range of situations - including dealing with the
problem of the case where the path being specified is relative
to another included file - rather than the page being displayed.

Any improvements welcomed.
