شمسی سازی تاریخ

درود

من از یک اسکریپت برای سایتم استفاده میکنم و متاسفانه با زبان PHP هم زیاد کارنکردم و مبتدی هستم.
یه تابع برای تاریخ و زمان سایتم استفاده شده که من میخوام به شمسی تبدیلش کنم کدش رو میزارم اینجا اگر دوستان کمک کنن ممنون میشم.

برای تبدیل تاریخ میلادی به شمسی
از این تابع ها استفاده کن
