   successive calls to dbmnextkey() it is possible to visit every
   key/value pair in the dbm database. For example:

   Example 1. Visiting every key/value pair in a DBM database
   <?php
   $key = dbmfirstkey($dbm_id);
   while ($key) {
       echo "$key = " . dbmfetch($dbm_id, $key) . "\n";
       $key = dbmnextkey($dbm_id, $key);
   }
   ?>
