Le contenu de cet article concerne la classe d'aide temporelle (exemple de code) implémentée en PHP. Elle a une certaine valeur de référence. Les amis dans le besoin peuvent s'y référer.
Dans le processus de travail, nous rencontrons souvent diverses opérations basées sur le temps, nous avons donc encapsulé une classe d'outils d'aide pour améliorer le taux de réutilisation du code
