Question

我试图在laravel的select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日期列表，从“ 2019-07-11”到“ 2019-07-25”。谁能为我提供控制器的代码片段来实现这一目标。

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

您可以使用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();

希望有帮助。
