Fonctions de calendrier PHP
Introduction au Calendar PHP
L'extension du calendrier contient des fonctions pour simplifier la conversion entre différents formats de calendrier.
Il est basé sur le compte des jours juliens (compte des jours juliens), et commence à compter à partir du 1er janvier 4713 avant J.-C.
Remarque :Pour convertir entre les formats de calendrier, vous devez d'abord convertir en compte des jours juliens, puis en le format de calendrier de votre choix.
Remarque :Julian Day Count (compte des jours juliens) et le calendrier julien ne font pas référence à la même chose !
Installation
To make these functions work, you must compile PHP with --enable-calendar.
PHP's Windows version has built-in support for the calendar extension, so the Calendar functions will work automatically.
