ReplaceIterator extends Collection
in package

Creates an iterator from another iterator that will modify each of the values by converting them using a callback function.

Properties

$_callback  : callable
The callback function to be used to transform values
$_innerIterator  : Traversable
A reference to the internal iterator this object is wrapping.

Methods

__construct()  : mixed
Creates an iterator from another iterator that will modify each of the values by converting them using a callback function.
__debugInfo()  : array<string, mixed>
Returns an array that can be used to describe the internal state of this object.
__serialize()  : array<string|int, mixed>
Returns an array for serializing this of this object.
__unserialize()  : void
Rebuilds the Collection instance.

Properties

$_callback

The callback function to be used to transform values

protected callable $_callback

$_innerIterator

A reference to the internal iterator this object is wrapping.

protected Traversable $_innerIterator

Methods

__construct()

Creates an iterator from another iterator that will modify each of the values by converting them using a callback function.

public __construct(iterable<string|int, mixed> $items, callable $callback) : mixed

Each time the callback is executed it will receive the value of the element in the current iteration, the key of the element and the passed $items iterator as arguments, in that order.

Parameters
$items : iterable<string|int, mixed>

The items to be filtered.

$callback : callable

Callback.

__debugInfo()

Returns an array that can be used to describe the internal state of this object.

public __debugInfo() : array<string, mixed>
Return values
array<string, mixed>

__serialize()

Returns an array for serializing this of this object.

public __serialize() : array<string|int, mixed>
Return values
array<string|int, mixed>

__unserialize()

Rebuilds the Collection instance.

public __unserialize(array<string|int, mixed> $data) : void
Parameters
$data : array<string|int, mixed>

Data array.

avg()

public avg([mixed $path = null ]) : mixed
Parameters
$path : mixed = null

cartesianProduct()

{@inheritDoc}

public cartesianProduct([callable|null $operation = null ][, callable|null $filter = null ]) : CollectionInterface
Parameters
$operation : callable|null = null

A callable that allows you to customize the product result.

$filter : callable|null = null

A filtering callback that must return true for a result to be part of the final results.
