很多年前，我做了一个第三方日历帮助程序，将公历日期转换为Jalali.我在Laravel服务中使用它.主要方法是jNow和jdate
Many years ago, I made a third party calendar helper to convert a Gregorian date to Jalali. I use it inside a Laravel service. The main methods are jNow and jdate
<?php
namespace Infrastructure\Services\Calendar;

{
list($hour, $minute, $second) = explode( ':', date( 'H:i:s', time() ) );
$today = time() - ( $hour*3600+$minute*60+$second );
if ( $timestamp > $today ) return 'امروز';
elseif ( $timestamp > $today-86400 ) return 'دیروز';
else return $this->jdate( $timestamp, false, true );
}
public function yearList($end=1970)
{
$year = (int)date('Y', time());
return $this->_yearList($year, $end);
}
private function _yearList($year, $end)
{
if ( $year < $end ) return array();
$years[] = $year;
while ( $year > $end ) {
$year--;
$years[] = $year;
}
return $years;
}
public function jYearList($end=1340)
{
$list = explode(' ', $this->jdate( date('Y-m-d-D H:i:s', time()), true, false ) );

return $this->_yearList($year, $end);
}
public function jNow()
