readdir

(PHP 3, PHP 4 )

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


// Note that !== did not exist until 4.0.0-RC2 <?php $handle=opendir('.'); echo "Directory handle: $handle\n"; echo "Files:\n"; while (($file = readdir($handle))!==false) {     echo "$file\n"; } closedir($handle);  ?>       

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 ..


<?php  $handle=opendir('.');  while (false!==($file = readdir($handle))) {      if ($file != "." && $file != "..") {          echo "$file\n";      }  } closedir($handle);  ?>
