[RESOLVED] Unable to access /data directory for opendir function

Joseph_Sliker

Hi; I believe I have run up against one of the many things I don't understand about servers.

BACKGROUND
Okay....I have an survey script that is located at the following url (slightly faked)

http://www.blahblahfakeurl.com/survey/survey1.htm

What appears in the browser url window when I actually go there is this:
http://www.blahblahfakeurl.com/survey1?path=/survey/

ACTUALLY, the .htm file is located in a subdirectory of /survey called /html, but there is something I don't understand about this, since the correct URL to actually us it is the one above and the following link does not work
http://www.blahblahfakeurl.com/survey/html/survey1.htm

PROBLEM
I want to be able to use the opendir() function to get a list of .dat files that live in another subdirectory of /survey called /data however, providing the value "data" in the $dir variable in the following function (or some variation with slashes and periods and all that) never seems to get me into that subdirectory, but leaving $dir=""; (empty) WILL very nicely allow me to see the files in the /html subdirectory.

function directory($dir,$filters) 
{ 
    $handle=opendir($dir); 
    $files=array(); 
    if ($filters == "all"){while(($file = readdir($handle))!==false){$files[] = $file;}} 
    if ($filters != "all") 
    { 
        $filters=explode(",",$filters); 
        while (($file = readdir($handle))!==false) 
        { 
            for ($f=0;$f<sizeof($filters);$f++): 
                $system=explode(".",$file); 
                if ($system[1] == $filters[$f]){$files[] = $file;} 
            endfor; 
        } 
    } 
    closedir($handle); 
    return $files; 
}

There is something sophisticated going on here that I do not understand.

I just found that a combination of opendir() and readdir() solves my problem.

<?php
$dir = "../data";
$dh  = opendir($dir);
while (false !== ($filename = readdir($dh))) {
    $files[] = $filename;
}
sort($files);
print_r($files);
?>

This will do what I need.
It turns out there is a bunch of Java script in the survey files (which I REALLY know nothing about) that probably makes all of the behaviour described above take place.
