PHP dir functionality

registered · Posted: Sun Oct 29, 2006 11:01 pm

I'm trying to debug someone's site, and I'm really getting stuck. The code is standard Patched (7.8 to be exact) and it is just not working correctly.

It is the "adding modules" code in admin/modules/modules.php
admin.php?op=modules

Specifically,

Code:




      $handle = opendir('modules');


      $modlist = "";


       while ($file = readdir($handle)) {


           echo "* : " . $file . "<br />";


         if ( (!ereg("[.]",$file)) ) {


            $modlist .= "$file ";


         }


       }

Now I've added the echo to see whether $file is being outputted. It isn't.
This code works fine outside this file. It will read the appropriate modules directory and output the files.

I've started commenting out lines to figure out the problem. Here is where I am stuck:

admin.php
calls the function GraphicAdmin() {

Which runs this code

Code:




      $linksdir = dir("admin/links");


      $menulist = "";


      while($func = $linksdir->read()) {


         if(substr($func, 0, 6) == "links.") {


            $menulist .= "$func ";


         }


      }


      closedir($linksdir->handle);

There doesn't seem to be a problem directly with this code. But when I comment it out, the above modules.php code works fine.

I cannot replicate this situation on my system. I was thinking it could be a path problem. But I've tried replicating it with the second code running in

/test.php
and including the first code in
/admin/modules/test.php

That seems to work fine. Anyone know of restrictions placed on opendir and dir that would prevent them to work? I just don't think its either of them, because I can copy this code into a seperate .php file and execute it fine.

Is $handle returning a valid pointer in $handle = opendir('modules');?
Have you turned errors on and checked your error log?

Try:

Code:

//Inspired by phoenix-cms at website-portals.net


//Absolute Nuke directory


define_once('NUKE_BASE_DIR', dirname(__FILE__) . '/');


//Absolute Nuke directory + includes


define('NUKE_BLOCKS_DIR', NUKE_BASE_DIR . 'blocks/');


define('NUKE_IMAGES_DIR', NUKE_BASE_DIR . 'images/');


define('NUKE_INCLUDE_DIR', NUKE_BASE_DIR . 'includes/');


define('NUKE_LANGUAGE_DIR', NUKE_BASE_DIR . 'language/');


define('NUKE_MODULES_DIR', NUKE_BASE_DIR . 'modules/');


define('NUKE_THEMES_DIR', NUKE_BASE_DIR . 'themes/');


define('NUKE_ADMIN_DIR', NUKE_BASE_DIR . 'admin/');


define('NUKE_DB_DIR', NUKE_INCLUDE_DIR . 'db/');


define('NUKE_ADMIN_MODULE_DIR', NUKE_ADMIN_DIR . 'modules/');


define('NUKE_FORUMS_DIR', (defined("IN_ADMIN") ? './../' : 'modules/Forums/'));





      $handle = opendir(NUKE_MODULES_DIR);


      $modlist = "";


       while ($file = readdir($handle)) {


           echo "* : " . $file . "<br />";


         if ( (!ereg("[.]",$file)) ) {


            $modlist .= "$file ";


         }


       }

Yes, nothing is giving an error message that I could use to debug.

I know I could do as technocrat's code and hard-code the paths.

It wouldn't explain why this code works just fine on many other systems and just stopped working for this specific one.

Is this account on the same server where the other one(s) work? If not, I suspect it's a php.ini issue.

Maybe a file or another path is conflicting.

I think in the end, I may just have to reinstall anyway. But I will try a clean phpNuke install and let you know

Don't know if this will help or not, but sometimes you can suppress the error and the code will execute. Just put an "@" sign in front of the opendir like so:

Code:

$handle = @opendir('modules');

and perchance would one site be running safe mode and the other not?

Took this right off php.net so no credit to me, but perhaps this will help evaders, I guess it Just basically handles $file in a more specific direction, Hope this works for you.

while (false !== ($file = readdir($handle))) {
echo "$file\n";
}

http://www.php.net/manual/en/function.readdir.php

Thats the link so you can see why I thought it pertenant to do this this way.

Dauthus, the @ symbol simply surpresses or holds back the error, if one is to be seen.

isn't that what i said???

Yea I saw that on php.net too. Wish it would fix it

If an error isn't being generated, how could be surpressed? Smile

evaders99, sorry but I must have misunderstood the issue. I made the assumption that since the code wasn't working properly you were getting some type of error. My bad.

It's funny because I use getcwd() and it returns the same working directory Smile

This is one of those I'm going to file under "mystified"

What version of PHP maybe there was a bug in their build

Posted: Tue Oct 31, 2006 1:49 pm

Evaders, what directory is being returned? The root?

My thinking is perhaps an addon or something is changing directories on you.

Another thing I was thinking was perhaps the buffer was getting full.
I have a few ideas but Im sure youll get it.

Yes the Nuke root. I was thinking something was changing their current directory. But it isn't

So oh well. They're trying to rebuild.

I reinstalled a clean version of phpNuke files (that I know work), and it is doing the same thing. Thought it was maybe the database, so I loaded up a new clean database. Same thing.

I'm at a loss

Have you tried modules/?

Just really weird to me as well.

Ive takin all the code, and tried it myself.

Id really like to see the full code, what version of nuke is it?

It's something with this server. But I'm not going to start going to compare every PHP setting. It is apparent that this server crashed at some point. So waiting on it to be reset and restarted.
