Oh, I see - you have to set $currentDir to whatever directory you want to read. Opening a null directory will always fail :) Put this at the top of your script (except of course put the directory you want to read). $currentDir = "/home/username/www"; Ben Gollmer Jatosoft, LLC http://www.jatosoft.com/ At 04:13 PM 6/29/2000 -0400, you wrote:
No, it's the error specified in your script: Error: Cannot open directory $currentDir. except $currentDir never shows up so all I see is: "Error: Cannot open directory" -Peter -----Original Message----- From: Ben Gollmer [mailto:ben@jatosoft.com] Sent: Wednesday, June 28, 2000 4:19 PM To: Peter Benoit Cc: php-general@lists.php.net Subject: RE: [PHP] I can't read directory contents What's the exact error? Something about "Access Denied"? Perhaps the user PHP is running as doesn't have read access to your directories. I'm not sure why a directory listing would be a security issue, especially for publicly accessible HTML files. That's something you'd have to ask your ISP...

Your script returns the Error message every time, which I guess means I can't read the contents of the directory? Is there a permission that needs to be set for this? What if my host says it's a security issue?

Try using the built-in filesystem functions in PHP. For example: $theDir = @opendir($currentDir); if (!$theDir) { 
         print ("<b>Error: Cannot open directory $currentDir.</b><br>");
} else { 
         while($filename = readdir($theDir))
         {
                 print $filename;
                 print ("<br>");
         }
} This will print out all the files in the directory $currentDir. Works under both NT and Linux. Just add an ereg or two in there to match html files, and you should be set. Ben Gollmer Jatosoft, LLC http://www.jatosoft.com/ At 03:23 PM 6/29/2000 -0400, you wrote:
Hi, I was using the following code on my Unix server which worked just fine. Now on my NT server, the host company states that I cannot read the directory contents and write them to this page because it's a security problem. Simply put, this should look for .htm files in a directory, and print
them
out on the page. It doesn't work now, but it works fine on my Unix host machine. Is this a security problem? Is there a setting I need on NT? Can't I do this with the standard read permissions? What do I need in order for a script like this to work? TIA, Peter <?php exec( "ls -la $dir",$lines,$rc); $count = count($lines) - 1; for ($i = 1; $i <= $count; $i++) {
