从当天开始接下来的6天？

Question

我尝试从当天开始接下来的6天存储,但是我很少会被困在这里如何在接下来的6天内存储$weekOfdays.是否有任何简单的功能可以做到这一点？

<?php
$weekOfdays = array();
$day = date('l');
$weekOfdays[] = $day;
$day = strtotime($day);

$next = strtotime("+6 day",$day);
$weekOfdays[] = date("l",$next);
var_dump($weekOfdays);
// output
// array (size=2)
// 0 => string 'Monday' (length=6)
// 1 => string 'Sunday' (length=6)
?>

我想看到数组是这样的

array (size=7)
  0 => string 'Monday' (length=6)
  1 => string 'Tuesday' (length=7)
  2 => string 'Wednesday' (length=9)
  3 => string 'Thursday' (length=8)
  4 => string 'Friday' (length=6)
  5 => string 'Saturday' (length=8)
  6 => string 'Sunday' (length=6)

Answer 1

这是一个不直接依靠自己进行数学运算的人:

$days   = [];
$period = new DatePeriod(
    new DateTime(), // Start date of the period
    new DateInterval('P1D'), // Define the intervals as Periods of 1 Day
    6 // Apply the interval 6 times on top of the starting date
);

foreach ($period as $day)
{
    $days[] = $day->format('l');
}

Answer 2

下面提到了一些样本的方法很多:

1)在循环中使用strtotime函数和temp $date变量

$date = date('Y-m-d'); //today date
$weekOfdays = array();
for($i =1; $i <= 7; $i++){
    $date = date('Y-m-d', strtotime('+1 day', strtotime($date)));
    $weekOfdays[] = date('l : Y-m-d', strtotime($date));
}
print_r($weekOfdays);

2)使用strtotime功能和+$i days当前日期

$date = date('Y-m-d'); //today date
$weekOfdays = array();
for($i =1; $i <= 7; $i++){
    $weekOfdays[] = date('l : Y-m-d', strtotime("+$i day", strtotime($date)));
}
print_r($weekOfdays);

3)使用DateTime类和modify方法

$date = date('Y-m-d'); //today date
$weekOfdays = array();
$date = new DateTime($date);

for($i=1; $i <= 7; $i++){
    $date->modify('+1 day');
    $weekOfdays[] = $date->format('l : Y-m-d');
}

print_r($weekOfdays);

4)使用DateTime班级和DateInterval班级

$date = date('Y-m-d'); //today date
$weekOfdays = array();
$date = new DateTime($date);

for($i=1; $i <= 7; $i++){
    $date->add(new DateInterval('P1D'));
    $weekOfdays[] = $date->format('l : Y-m-d');
}

print_r($weekOfdays);

5)使用DatePeriod,DateInterval和DateTime类

$date = date('Y-m-d', strtotime('+1 day')); //tomorrow date
$weekOfdays = array();
$begin = new DateTime($date);
$end = new DateTime($date);
$end = $end->add(new DateInterval('P7D'));
$interval = new DateInterval('P1D');
$daterange = new DatePeriod($begin, $interval ,$end);

foreach($daterange as $dt){
    $weekOfdays[] = $dt->format('l : Y-m-d');
}

print_r($weekOfdays);

今天是4月12日星期二,所以所有代码的输出将是:

Array
(
    [0] => Wednesday : 2016-04-13
    [1] => Thursday : 2016-04-14
    [2] => Friday : 2016-04-15
    [3] => Saturday : 2016-04-16
    [4] => Sunday : 2016-04-17
    [5] => Monday : 2016-04-18
    [6] => Tuesday : 2016-04-19
)
