append

This is used to append an element to an assigned array. If you append to a string value, it is converted to an array value and then appended to. You can explicitly pass name/value pairs, or associative arrays containing the name/value pairs. If you pass the optional third parameter of true, the value will be merged with the current array instead of appended.

// passing name/value pairs
$smarty->append("Name","Fred");
$smarty->append("Address",$address);

// passing an associative array
$smarty->append(array("city" => "Lincoln","state" => "Nebraska"));
