the problem is when i want to expand a site with a new application,
usually that comes in its own directory. but, to include the new
application i have to wrap it inside the main directory -- in this
case /a/b/current .... which requires of course that i call
first /a/b/current/common.php which starts the sessions, sends the
cookies, checks post variables.
but that doesn't work, really, because then all of the includes for the
application says "include(main.php)" ... but php thinks it's
in /a/b/current not in /a/b/current/d/ ..... so it says "cannot find
include file "main.php" in path: path:::;; .."
my wish list:
1) applications came with a configurable directory to preced every
include or require.
like, change "include(main.php)" --> include( $config[dir] .
"main.php" )
alternatively,
2) all applications come with a unique prefix affixed to the files so
they can simply be laid out in the document root and be visually and
mentally and upgradably separate from the files of the other
applications existing in the same $_SERVER[document_root]
i honestly don't understand the include mechanism. i have encountered
many cases ( sorry, can't be explicit) where a file which was 2 includes
away wouldn't have any variables in the main script, unless i added a
line to include that file in that file directly.
as an example:
/a/b/current/index.php
include("common.php");
include("lib/functions2.php");
/a/b/current/lib/functions2.php
you would think would be able to simply run with what was
included "above" it but you can't. you have to redeclare
include_once($g4[bbs]. "/dbconfig.php");
include_once($g4[bbs]. "/common.php");
the include of the common.php file.
i am looking for the rule for that.... they say it's global, but it's
not. However, i found that if you include "common.php" again then it
finds the functions it misses, because it itself was included by
"common.php". as if the direction of the includes matters .........
explicitly:
if common.php includes lib/functions.php common.php can access
lib/functions.php
but if lib/functions.php needs common.php then lib/functions.php needs
to include common.php
is that correct?
because of these problems, when i have to wrap another application
inside an existing SKIN and common.php, i end up changing the file
names, running a SED script to replace all occurrences of filenames with
their newly-uniquely-prefixed-names .....
