A tiny code to convert date into Jalali calendar using Pure PHP code without extra library and code.

array jalaliDate(?int $year, ?int $month, ?int $day)

date_default_timezone_set('Asia/Tehran');
// OR
date_default_timezone_set('America/New_York');

First you need to include the library by include "src/JalaliDate.php"; next:

print_r(jalaliDate()); // It will return today date in Jalali date system.
// Array
// (
//     [year] => 1401
//     [month] => 08
//     [day] => 04
// )

print_r(jalaliDate(2022, 9, 26));
// Array
// (
//     [year] => 1401
//     [month] => 07
//     [day] => 04
// )
