PHP help needed - directory listing problem

[hitchhiker]

Hi,

 

I'm using the following code to list the files in a directory. The problem is that besides the correct files it also returns two extra files named '.' and '..'!

 

This is the code:

 

<?php

$direct = "image/";

if ($handle = opendir('images/')) {
   while (false !== ($file = readdir($handle))) {
         echo ("<p>" . $file . "</p>");
           }
  closedir($handle);
}
?> 

 

And it returns this:

 

.

..

image1.gif

image2.gif etc.

 

I can't understand what the '.' and '..' are there for as they are not in the actual directory on the server?

 

Also, if there's nothing I can do about this, how would I get round it i.e. ignore anything found called '.' or '..'.

I'm sure a more UNIX/Linux-savvy person will have a better explanation, but those dots represent the current level and parent level directories...

 

So your code is doing exactly as it is told...

The . is the current directory and the .. is the parent directory - they are automagic parts of the linux directory listing. Try using:

 

if ($file != "." && $file != "..") {

echo "<p> $file </p>\n";

}

 

rather than your echo statement.

Brilliant! Thanks - works like a treat!

 

<?php

$direct = "image/";

if ($handle = opendir('images/')) {

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

         if ($file != "." && $file != "..") {

         echo ("<p>" . $file . "</p>");
         }
  }

  closedir($handle);
}
?>

Just to point out these directories also exist under windows.
