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:
Slice
sequence<Fruit> FruitPlatter;
You can create an instance of FruitPlatter as shown below:
PHP
// 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.
