날짜 선택

PHP에서 날짜 선택을 깔끔하게 하는 코드를 적어둔다.

<?php
//---- 오늘 날짜
$thisyear = date("Y");
$thismonth = date("m");
$today = date("d"); // 1, 2, 3, ..., 31

//------ $year, $month 값이 없으면 현재 날짜
$year = isset($_GET['year']) ? $_GET['year'] : $thisyear;
$month = isset($_GET['month']) ? $_GET['month'] : $thismonth;
$day = isset($_GET['day']) ? $_GET['day'] : $today;

$start_date = date("Y", mktime(0, 0, 0, date("m"), date("d"), date("Y") - 1));
$end_date = date("Y", mktime(0, 0, 0, date("m"), date("d"), date("Y") + 3));
?>
