problems with dbase

Hi,

we have some problems with dbase running php4.
The creation does not work at all.

php4:
http://ns5.ovh.net/test.php3 (phpinfo)
http://ns5.ovh.net/creation.php3

php3:
http://ns3.ovh.net/test.php3 (phpinfo)
http://ns3.ovh.net/creation.php3

creation.php3 is

<?

// "database" name
$dbname = "base/test.dbf";

// database "definition"
$def =
array(
array("date",     "D"),
array("name",     "C",  50),
array("age",      "N",   3, 0),
array("email",    "C", 128),
array("ismember", "L")
);

// creation
if (!dbase_create($dbname, $def))
print "<strong>Error!</strong>";

?>
