#### [9fans] Include guards and multiple includes

-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1

I'm trying to convince some non-believers that include files should
not include other include files, and that instead they should state
their dependencies; they want hard data before they commit to such a
scheme.

Is there some study kicking around that I could point them at rather
than re-factor our code base and time the resulting builds?  I know

I'm fairly certain it's a stylistic/maintainability issue on Plan 9,
not an efficiency one.

I think that one of the best arguments for organising header files as
Plan 9 does is the mess that /usr/include has become on (l)unix.  It's
almost 20MB on Suse 9.1.

Here's an interesting exercise for people who don't see a problem with
how (l)unix organises /usr/include:

Ask someone (ideally a manager, the higher the rank, the better) to
find out where under /usr/include on Linux the type time_t is defined
and the signal SIGINT is declared without using grep or any
equivalent; they should trace through the include files visually.  If
they return with the correct answers and aren't disgusted with the
mess under /usr/include, slap some pointy hair on them.

I think this has more to do with minimising the preprocessor logic. I
like the plan 9 include tree more than the traditional unix include
mess. In my programs I dont use macros anywhere. none. nada. zero.

If one could only get rid of the preprocessor...

include files not being included
Hello, I'm running php 5.2.5 installed from ports on a FreeBSD machine with apache2 as the webserver. I've got php set up properly, but it doesn't include include files. If i do a phpinfo() in a file that works telling me php file processing is working fine. Yet if i have something like for an example: <html> <head> <title>Test of includes</title> </head> <body> <h1><? include "test-include.php"; ?></h1> <p>The above should have been included.</p> </body> </html> and in test-include.php i have: This is a test include i get only the line: The above should have been included. I did not enter php mode in the test include file because of the <? and ?> sygnifying i'm already in php mode, but i tried it anyway and that didn't make a difference, either case the file was not included. This was working previously with php4, i know about the global variables not being allowed in php5, has anything else changed in regards to include files? Any suggestions welcome. Thanks. Dave.

Includes and sub-includes Hello all, We are currently changing our web server and, in the process, updating PHP version from 4.3.0 to 4.3.5. The problem we've got is that our way to include some files in other ones is no more working properly. The message we are getting looks like: "PHP Warning: main(..\db.inc.php): failed to open stream: No such file or directory in ..." Say we have this file structure: myApplication (dir) index.php include (dir) db.inc.php authentification (dir) user.inc.php login.php - user.inc.php includes db.inc.php calling "include('..\db.inc.php')" - both login.php and index.php includes user.inc.php - index.php calls "include('include\authentification\user.inc.php')" - login.php calls "include('..\user.inc.php')" I know I could solve this problem by making those the includes absolute instead of relative but I would prefer to let it relative for some developement reason. myApplication actually contains many other files calling "include('..\db.inc.php')" so I don't want to move this file.

Folks, I have a virtual server with an ISP and I had a web based application available for a customer to try out - it worked fine up until three weeks ago - nothing has changed since then (I am the only one with root password unless the ISP took control without my permission but I'd doubt this). I have Virtual (Named) Hosting enabled and I can test it via individual url's responding appropriately. On one specific URL I have an include as the first line... and there are no error messages in the error log file, the html is rendered just fine but various variables defined during the include are expected to help fill in the html. This was not happening hence I investigated. To start with, my index.htm file includes a standard.php file. The standard.php file leads with <? die("here I am"); ?> and I still get my index.htm page and no "here I am". I have tried a phpinfo() too, and nothing happens. In my index.htm file I have placed phpinfo and that works... as does the "die()" too. I know my pages are being caught by the php engine because I can call a temp file with .htm or .php and both are rendered as expected by php. The only thing I do know that might be related to this is if some safe mode (php_safe?) was enabled. My standard.php file lives outside my directory tree...

However, I have found nothing in 6.4.9, 6.4.7 (however R3 mentions an undefined behavior if /* is between the braces or double quotes of the include directive) or 6.10 and I am getting to the conclusion that this is an undefined behavior.

include()
I don't completely understand the documentation for the include() function: "Files for including are first looked in include_path relative to the current working directory and then in include_path relative to the directory of current script. E.g. if your include_path is ., current working directory is /www/, you included include/a.php and there is include "b.php" in that file, b.php is first looked in /www/ and then in /www/include/. " How do you know where "the current working directory" is? Mike wrote: > How do you know where "the current working directory" is? If you mean, how do you find out programmatically what it is, use the getcwd() function. If you mean, how do you as a programmer know what it should be ahead of time, it's usually the directory containing the top-level script that's being executed. (This may not hold true for command-line execution, but should for web execution.) So if the web server is loading up A.php, and A.php include()s B.php, in B.php the working directory is still the location of A.php.
