我想检查DB中存储的某个日期,如果此日期是在此财政年度中,它将打印有效,如果不是,则打印strong>无效
这是我的php代码:
$init_date= date("2016/07/01");
$end_date= date("2017/06/30");
$i_date = strtotime($init_date);
$e_date = strtotime($end_date);
$date_db= strtotime($date);// this $date is retrieved from my DB
if ($e_date > $date_db && $i_date < $date_db)
{ echo "valid";}
else { echo "invalid";}
,但问题是我不想设置起点,而结束日期则是有机化的方法吗?因为它将每年更新
这样,您的脚本将有点 dynamic 。
// the below snippet checks the date retrieved from database
// against fiscal periods between years 2000 and 2050 and return the
// valid dates
$endYear=2000;
while($endYear<=2050) {
$end = $endYear.'/06/30';
$endDate = DateTime::createFromFormat('Y/m/d', $end);
$initDate = DateTime::createFromFormat('Y/m/d', $end);
$initDate = $initDate->sub(new DateInterval('P1Y'))->add(new DateInterval('P1D'));
$ddb = '2016-09-27';
$dateFrodDB = DateTime::createFromFormat('Y-m-d', $ddb);
if ($dateFrodDB>=$initDate && $dateFrodDB<=$endDate)
{ echo "validn";
echo "tStartDate->"".$initDate->format("Y-m-d").""n";
echo "tEndDate->"".$endDate->format("Y-m-d").""n";
echo "tDateFromDatabase->"".$dateFrodDB->format("Y-m-d").""n";
}
$endYear++;
}
/* output
valid
StartDate->"2016-07-01"
EndDate->"2017-06-30"
DateFromDatabase->"2016-09-27"
*/
在PHP沙盒上检查此信息
尝试这个,
<?php
$start_date = date('Y-m-d', strtotime(str_replace("/", "-", $initdate)));
$end_date = date('Y-m-d', strtotime(str_replace("/", "-", $end_date)));
$new_date = date('Y-m-d', strtotime(str_replace("/", "-", $date)));
if (($start_date < $new_date && $new_date < $end_date) || ($end_date < $new_date && $new_date < $start_date)) {
echo "valid";
} else {
echo 'invalid';
}
