PHP 8.4.1 Released!

The Collection interface

(PECL ds >= 1.0.0)

Einführung

Collection is the base interface which covers functionality common to all the data structures in this library. It guarantees that all structures are traversable, countable, and can be converted to json using json_encode().

Interface-Übersicht

interface Ds\Collection extends Countable, IteratorAggregate, JsonSerializable {
/* Methoden */
public clear(): void
public isEmpty(): bool
public toArray(): array
/* Geerbte Methoden */
}

Changelog

Version Beschreibung
PECL ds 1.4.0 Collection implements IteratorAggregate now instead of just Traversable. (This change came to the polyfill in 1.4.1.)
