PHP Mapping for Sequences

A Slice sequence maps to a native PHP indexed array. The first element of the Slice sequence is contained at index 0 (zero) of the PHP array, followed by the remaining elements in ascending index order.

Consider this example:

sequence<Fruit> FruitPlatter;

You can create an instance of FruitPlatter as shown below:

// Make a small platter with one Apple and one Orange
$platter = array(Fruit::Apple, Fruit::Orange);

The Ice run time validates the elements of an array to ensure that they are compatible with the declared type and raises InvalidArgumentException if an incompatible type is encountered.
