Im having the same kind of problem.
$conn = oci_pconnect('scott','tiger','');
$query = 'create user :user_id identified by :user_password';
$stid = oci_parse($conn, $query);
oci_bind_by_name($stid,":user_id",$this->user_id);
oci_bind_by_name($stid,":user_password",$this->user_password);
oci_execute($stid);
oci_close($conn);
