Constructing Arrays

Indexed arrays​

ZYMBA
$numbers = [1, 2, 3, 4, 5];
$names   = ["Alice", "Bob", "Charlie"];
$empty   = [];

Associative arrays​

Use key: value syntax:

ZYMBA
$person = [name: "Alice", age: 30, city: "NYC"];
$config = [host: "localhost", port: 3306, debug: true];

Nested arrays​

ZYMBA
$products = [
    [id: 1, name: "Widget", price: 9.99],
    [id: 2, name: "Gadget", price: 29.99],
    [id: 3, name: "Gizmo",  price: 49.99]
];

Array generators​

ZYMBA
// Range of numbers
$range = @Array.createRange(1, 5, 1);  // [1, 2, 3, 4, 5]

// Filled array
$zeros = @Array.createIndex(5, 0);     // [0, 0, 0, 0, 0]

// Combine keys and values
$map = @Array.combine(["a", "b", "c"], [1, 2, 3]);
// [a: 1, b: 2, c: 3]

// Create associative array: all keys share the same value
$flags = @Array.createAssociative(["read", "write", "exec"], true);
// [read: true, write: true, exec: true]

// Repeat array contents
$repeated = @Array.repeat([1, 2], 3); // [1, 2, 1, 2, 1, 2]

// Pad array to a target length
$padded = @Array.pad([1, 2, 3], 6, 0); // [1, 2, 3, 0, 0, 0]
