A Slice dictionary maps to a native PHP associative array. The PHP mapping does not currently support all Slice dictionary types, however, because native PHP associative arrays support only integers and strings as keys.
A Slice dictionary whose key type is an enumeration or one of the primitive types boolean
, byte
, short
, int
, or long
is mapped as an associative array with an integer key.
Info |
---|
Boolean values are treated as integers, with false equivalent to 0 (zero) and true equivalent to 1 (one). |
A Slice dictionary with a string
key type is mapped as an associative array with a string key. All other key types cause a warning to be generated.
Here is the definition of our EmployeeMap
:

{zcode:slice}
dictionary<long, Employee> EmployeeMap;
{zcode} |
You can create an instance of this dictionary as shown below:
Wiki Markup |
---|
{zcode:php}
$e1 = new Employee;
$e1->number = 42;
$e1->firstName = "Stan";
$e1->lastName = "Lipmann";
$e2 = new Employee;
$e2->number = 77;
$e2->firstName = "Herb";
$e2->lastName = "Sutter";
$em = array($e1->number => $e1, $e2->number => $e2);
{zcode} |
The Ice run time validates the elements of a dictionary to ensure that they are compatible with the declared type; InvalidArgumentException
exception is raised if an incompatible type is encountered.
