# readdir

readdir -- read entry from directory handle

## Description

`string readdir`(int dir_handle);

Returns the filename of the next file from the directory. The filenames are not returned in any particular order.

Example 1. List all files in the current directory

      1
      2 <?php
      3 $handle=opendir('.');
      4 echo "Directory handle: $handle\n";
      5 echo "Files:\n";
      6 while ($file = readdir($handle)) {
      7     echo "$file\n";
      8 }
      9 closedir($handle);
     10 ?>
     11

Note that readdir() will return the . and .. entries. If you don't want these, simply strip them out:

Example 2. List all files in the current directory and strip out . and ..

      2 <?php
      3 $handle=opendir('.');
      4 while ($file = readdir($handle)) {
      5     if ($file != "." && $file != "..") {
      6         echo "$file\n";
      7     }
      8 }
