?>

stukje van de index waar ik nldatum() gebruik:

echo "<br /><br /><br />Datum: <span style="font-weight: bold;">".nldatum($row[datum])."</span><br /><br />";

voorderest gebruik ik hem nergens.
ik include hem zo:

include(nieuws/datum.php);

hopelijk lukt het iemand wel
kenzo

Includen met nldatum();?

hoeft niet
