Plus tôt, nous avons expliqué la
méthode de seuil, qui génère chaque valeur limite du calendrier
méthode caculate, qui calcule le nombre de jours et le style du calendrier
draw, dessine des tableaux et des paramètres tr et td dans le tableau
Dans cette section, nous les encapsulons dans une classe Calendar, puis nous la référençons sur la page frontale. Vous pouvez appeler cette classe lorsque vous réalisez d'autres projets similaires. à l'avenir.
Ce fichier de classe est créé avec le nom calendrier.php.
