Class ReplaceIterator

__construct()source public

__construct( array|Traversable $items , callable $callback )

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

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

array|Traversable $items

The items to be filtered.

callable $callback

Callback.

Throws

Overrides

current()source public

current( )

Returns the value returned by the callback after passing the current value in the iteration

Returns

Overrides

unwrap()source public

unwrap( )

We perform here some strictness analysis so that the iterator logic is bypassed entirely.

Returns

Overrides

__debugInfo()source public

__debugInfo( )

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

Returns

count()source public

count( )

Throws an exception.

Issuing a count on a Collection can have many side effects, some making the Collection unusable after the count operation.

Throws

serialize()source public

serialize( )

Returns a string representation of this object that can be used to reconstruct it

Returns

Implementation of

unserialize()source public

unserialize( string $collection )

Unserializes the passed string and rebuilds the Collection instance

Parameters

string $collection

The serialized collection
