dba_firstkey — Lit la première clé DBA
   dba_firstkey() retourne la première clé
   de la base de données spécifiée par handle 
   et y place le pointeur interne de clé. Cela permettra de traverser la base.
  
   Retourne la clé en cas de succès ou false si une erreur survient.

?>Looks like Jacky is using some DB object? I don't know if it's native to PHP or written on it's own... Anyways this is what I use:
$DBCon = dba_open("/tmp/test_db.db2", "r", "db2") or die("Uh oh, can't open the database :(");
if ($the_key = dba_firstkey($DBCon)) do {
    print("Key: $the_key    Value:");
    print dba_fetch($the_key, $DBCon);
    print("<BR>");
} while ($the_key = dba_nextkey($DBCon));
print ("<BR><BR><BR>Well looks like we're done here :-)");
