Macros

• mapToCollectionFrom
• mapToCollection
• positive
• recursiveToArrayFrom
• recursiveToArray

mapToCollectionFrom

Static method: Maps all arrays/objects recursively to a collection object of collections, which allow nested function calling.

$collection = Collection::mapToCollectionFrom([['test' => 1], 2, 3]);

$collection->get(0)->get('test'); // returns 1

// Item has a toArray() public method, then it can be wrapped into a collection like this:
$collection = Collection::mapToCollectionFrom([Item(), Item()], true);

positive

Returns a boolean value, if the collection contains elements or not.

Collection::make([1, 2, 3])->positive() // returns true
Collection::make()->positive() // returns false

recursiveToArrayFrom

Static method: Like mapToCollectionFrom it maps all arrays/objects recursively to an array.

// Item has a toArray() public method, then it can be wrapped into the collection like this:
$array = Collection::recursiveToArrayFrom(['item1' => Item(), 'item2' => Item()]);
