    Put your links in a txt file called links.txt and run the code below

    
<?php
$dirs = file("links.txt");
    shuffle($dirs);
    $folders = explode("\n", $dirs[0]);
    $dir_folder = $folders[0];
    echo $dir_folder;
?>

    I would not use a file to do this - I would use an array that you preset or populate with a database.

    Example of Array

    I would recommend to populate with a database - as it would be much more simple to just to ORDER BY rand in the query

    Array Way

    
<?php

  $array_of_links = array(
                                      array('url' => 'http://www.myurl.com/1/', 'anchor' => 'Anchor Text', 'image_src' => 'http://.../image.jpg'),
                                      array('url' => 'http://www.myurl.com/2/', 'anchor' => 'Anchor Text', 'image_src' => 'http://.../image.jpg'),                                 
                                      array('url' => 'http://www.myurl.com/3/', 'anchor' => 'Anchor Text', 'image_src' => 'http://.../image.jpg'),                                 
                                      array('url' => 'http://www.myurl.com/4/', 'anchor' => 'Anchor Text', 'image_src' => 'http://.../image.jpg'),                                 
                                      array('url' => 'http://www.myurl.com/5/', 'anchor' => 'Anchor Text', 'image_src' => 'http://.../image.jpg')                                 

);

  // next all you have to do is just get random
  $randomized_links = shuffle($array_of_links);

  // to use them
  foreach( $randomized_links as $link ):
      
     echo "<a href='" . $link['url'] . "'>" . "<img src='" . $link['image_src'] . "' alt='" . $link['anchor'] . "'>" . "</a>";  
  
  endforeach;
?>
    Code (markup):
    Note: This Code May Break I didn't test the code - but you should get the general idea from it.
