La classe DateTime

(PHP 5 >= 5.2.0, PHP 7, PHP 8)

Introduzione

Rappresentazione di una data e ora.

Questa classe si comporta come DateTimeImmutable, eccetto che gli oggetti si modificano quando vengono chiamati dei metodi di modifica come DateTime::modify().

Avviso

Chiamare metodi sugli oggetti della classe DateTime cambierà le informazioni incapsulate in questi oggetti, se si vuole prevenirlo si dovrà utilizzare l'operatore clone per creare un nuovo oggetto. Utilizzare DateTimeImmutable invece di DateTime per ottenere questo comportamento raccomandato per impostazione predefinita.

Log delle modifiche

Versione	Descrizione
7.2.0	Le costanti della classe DateTime sono ora definite in DateTimeInterface.
7.1.0	Il costruttore DateTime ora include i microsecondi attuali nel valore costruito. Prima di questo, inizializzava sempre i microsecondi a `0`.
