lithium\util\Collection::toArray()

public static method

Exports a Collection instance to an array. Used by Collection::to().

Parameters

mixed $data
Either a Collection instance, or an array representing a Collection's internal state.
array $options
Options used when converting $data to an array:
- 'handlers' array: An array where the keys are fully-namespaced class names, and the values are closures that take an instance of the class as a parameter, and return an array or scalar value that the instance represents.

Returns

array

Returns the value of $data as a pure PHP array, recursively converting all sub-objects and other values to their closest array or scalar equivalents.
