thank you techer this! but !i try that, it show ****Parse error: syntax error, unexpected '[' **** why??? have something wrong?
Most likely your PHP is VERY old.
i sorry! i use PHP Information Version 5.2.6 maybe to old!
FYI. Even PHP 7.4 is almost end of life. https://www.php.net/supported-versions.php
On line 106, the variable $date is undefined, but it's ok if does not need to invoke method convertSolarMonthToLunar().
if ($year === static::MIN_YEAR && $month <= 2 && $date <= 9)
On line 106, the variable $date is undefined, but it's ok if does not need to invoke method convertSolarMonthToLunar(). if ($year === static::MIN_YEAR && $month <= 2 && $date <= 9)
That early return seems to be wrong and unnecessary. I've updated this gist to remove it.
