如何获取给定日期前后 7 天的日期范围并填充到选择中 - Laravel

Question

我试图在 laravel 的选择字段中获取特定日期之前和之后的 7 个日期的日期列表。 例如，如果特定日期是“2019-07-18”，我想在选择字段中填充从“2019-07-11”到“2019-07-25”的日期列表。 任何人都可以用代码 sn-p 来帮助我实现这一点。

Answer 1

function getAgoDays($specDay, $days, $format = 'Y-m-d') {
    $d = date('d', strtotime($specDay)); 
    $m = date('m', strtotime($specDay)); 
    $y = date('Y', strtotime($specDay));
    $dateArray = array();
    for($i=1; $i<=$days; $i++) {
        $dateArray[] = '"' . date($format, mktime(0,0,0,$m,($d-$i),$y)) . '"'; 
    }
    return array_reverse($dateArray);
}
function getBeforeDays($specDay, $days, $format = 'Y-m-d') {
    $d = date('d', strtotime($specDay)); 
    $m = date('m', strtotime($specDay)); 
    $y = date('Y', strtotime($specDay));
    $dateArray = array();
    for($i=1; $i<=$days; $i++) {
        $dateArray[] = '"' . date($format, mktime(0,0,0,$m,($d+$i),$y)) . '"'; 
    }
    return $dateArray;
}

使用

$agoDays = getAgoDays('2019-07-18', 7, 'Y-m-d');
echo '<pre>';
print_r($agoDays);
echo '</pre>';
$agoDays = getBeforeDays('2019-07-18', 7, 'Y-m-d');
echo '<pre>';
print_r($agoDays);
echo '</pre>';

Answer 2

你可以使用carbon period:

$givenDate = "2019-07-18";
$dateMinusOneWeek = Carbon::parse($givenDate)->subWeek()->format('Y-m-d');
$datePlusOneWeek = Carbon::parse($givenDate)->addWeek()->format('Y-m-d');

$period = CarbonPeriod::create(dateMinusOneWeek , datePlusOneWeek);

//You can iterate over the period
foreach ($period as $date) {
    echo $date->format('Y-m-d');
}

//Or convert the period to an array of dates
$dates = $period->toArray();

希望对你有帮助。
