Help adding to my script

[gavakie]

Im new to php and am learning slowly .  I have this below which populates a drop down.  After I select the drop down I need it to write the path of all the files from the choice of my drop down.  Any help would be appreciated.

 

<select name="mydropdown">

<?php

$out1 = '';

if ($handle = opendir($_SERVER['DOCUMENT_ROOT'] . '\files')) {

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

 

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

 

            $fileName =  $file;

            echo '<option value="' . $file . '">' . $fileName . '</option>';

$out1 .= '<span>"'. $file .'"</span>';

        }

    }

    closedir($handle);

}

?>

</select
