您好，我有一个函数可以返回从当天算起过去 30 天(不包括当前日期)的信息。功能如下
function getLastNDays($days, $format = 'd-m-Y'){
$m = date("m"); $de = date("d")-1; $y= date("Y");
$dateArray = array();
for($i=0; $i<=$days-1; $i++){
$dateArray[] = date($format, mktime(0,0,0,$m,($de-$i),$y));
}
$dateArray[] = 'x';
return array_reverse($dateArray);
}
所以我正在使用这个功能
$sevenarr = getLastNDays(30);
它返回了我这个结果
Array
(
[0] => x
[1] => 19-06-2018
[2] => 20-06-2018
[3] => 21-06-2018
[4] => 22-06-2018
[5] => 23-06-2018
[6] => 24-06-2018
[7] => 25-06-2018
[8] => 26-06-2018
[9] => 27-06-2018
[10] => 28-06-2018
[11] => 29-06-2018
[12] => 30-06-2018
[13] => 01-07-2018
[14] => 02-07-2018
[15] => 03-07-2018
[16] => 04-07-2018
[17] => 05-07-2018
[18] => 06-07-2018
[19] => 07-07-2018
[20] => 08-07-2018
[21] => 09-07-2018
[22] => 10-07-2018
[23] => 11-07-2018
[24] => 12-07-2018
[25] => 13-07-2018
[26] => 14-07-2018
[27] => 15-07-2018
[28] => 16-07-2018
[29] => 17-07-2018
[30] => 18-07-2018
)
所以我现在想要的是将结果天显示为周。所以到目前为止我还无法弄清楚如何使用上面的函数来做到这一点。请帮我一些逻辑，我如何更新我的功能，以便我获得最后所需天数的周数。例如最后 30 天它将把天转换为周
我想要的输出是
Array
(
[0] => Array
(
['start-date'] => 18-07-2018
['end-date'] => 12-07-2018
)
[1] => Array
(
['start-date'] => 11-07-2018
['end-date'] => 5-07-2018
)
[2] => Array
(
['start-date'] => 04-07-2018
['end-date'] => 28-06-2018
)
[3] => Array
(
['start-date'] => 27-06-2018
['end-date'] => 21-06-2018
)
[4] => Array
(
['start-date'] => 20-06-2018
['end-date'] => 19-06-2018
)
期望的输出
[weekArray] => Array
(
[1] => Array
(
[0] => 2018-06-19
[1] => 2018-06-20
[2] => 2018-06-21
[3] => 2018-06-22
[4] => 2018-06-23

[6] => 2018-07-02
)

最佳答案
检查以下函数以将天数范围转换为周数。我已将星期日视为一周的第一天。
<?php
function getLastNDays($days, $format = 'Y-m-d'){
$retunData = array();
$m = date("m"); $de = date("d")-1; $y= date("Y");
$dateArray = array();
for($i=0; $i<=$days-1; $i++){
$dateArray[] = date($format, mktime(0,0,0,$m,($de-$i),$y));
}
//$dateArray[] = 'x';
$resultArray = array_reverse($dateArray);
// After get the date Range find out Statrt & End date
$start_date = $resultArray[0];
$end_date = $resultArray[count($resultArray)-1];
$from_date = new DateTime($start_date);
$to_date = new DateTime($end_date);
$interval = new DateInterval('P1D');
$dateRange = new DatePeriod($from_date, $interval, $to_date);
$week_number = 1;
$weekArray = array();
foreach ($dateRange as $key => $date) {
$weekArray[$week_number][] = $date->format('Y-m-d');
$mod = $key%7;
if($mod == 6){
$week_number++;
}
/*
if ($date->format('w') == 6) {
$week_number++;
}
*/
}
$retunData['weekArray'] = $weekArray;
//Get the Start & End Date each week.
$weekrange = array_map(function($w) {
return 'start: ' . array_shift($w)
. ', end: ' . array_pop($w); },
$weekArray);
$retunData['weekRange'] = $weekrange;
return $retunData;
}
$retunData = getLastNDays(30); // Call your custom function.
echo '<pre>';
print_r($retunData);
exit;
?>
Your Output will be as per the date range.
