问题描述
创建下面的制作时间以显示每两周一次的日期
Created the make time below to display biweekly dates
<?php
$date1 = "07/05/2013";
$date2 = date('M j, Y', strtotime($date1 . " + 14 day"));
$date3 = date('M j, Y', strtotime($date2 . " + 14 day"));
$date4 = date('M j, Y', strtotime($date3 . " + 14 day"));
$date5 = date('M j, Y', strtotime($date4 . " + 14 day"));
$date6 = date('M j, Y', strtotime($date5 . " + 14 day"));
$date7 = date('M j, Y', strtotime($date6 . " + 14 day"));
$date8 = date('M j, Y', strtotime($date7 . " + 14 day"));
$date9 = date('M j, Y', strtotime($date8 . " + 14 day"));
$date10 = date('M j, Y', strtotime($date9 . " + 14 day"));
$date11 = date('M j, Y', strtotime($date10 . " + 14 day"));
$date12 = date('M j, Y', strtotime($date11 . " + 14 day"));
$date13 = date('M j, Y', strtotime($date12 . " + 14 day"));
$date14 = date('M j, Y', strtotime($date13 . " + 14 day"));
$date15 = date('M j, Y', strtotime($date14 . " + 14 day"));
$date16 = date('M j, Y', strtotime($date15 . " + 14 day"));
$date17 = date('M j, Y', strtotime($date16 . " + 14 day"));
$date18 = date('M j, Y', strtotime($date17 . " + 14 day"));
?>
如何让它按月分组?让我们想知道八月或十二月的日期有多少。另外如果我想在年底前得到多少日期?帮助手将不胜感激。
How can I get it to group together by Month? Let say I want to know how many dates land in August, or December. Also if I wanted to get how many dates till end of the year? Helping hand will be greatly appreciated.
推荐答案
尝试这样:
<?php
// initiate months
$month_arr = Array();
for ($i=1; $i<=12; $i++){
// no. of dates
$month_arr[$i] = 0;
}
$date_arr = Array();
$date_start = "07/05/2013";
$date_arr[] = date('M j, Y', strtotime($date_start));
for ($i=1; $i<=17; $i++){
$date_temp = date('M j, Y', strtotime($date_arr[$i-1] . " + 14 day"));
$month = date('n', strtotime($date_temp));
$month_arr[$month] += 1;
$date_arr[] = $date_temp;
}
foreach ($month_arr as $k => $v){
echo "<BR>Month: " . $k . ", No. of dates: " . $v;
}
// all dates
echo "<BR>All dates<BR>";
var_dump ($date_arr);
?>
您可以扩展这个逻辑,将实际日期分为几个月,而不是仅将日期计数一个月。这是解决方案:
You can extend this logic to group the actual dates by months rather than getting only the count of dates in a month. This is the solution for that:
<?php
// initiate months
$month_arr = Array(
'January' => Array('num_dates'=>0, 'dates'=>Array()) ,
'February' => Array('num_dates'=>0, 'dates'=>Array()),
'March' => Array('num_dates'=>0, 'dates'=>Array()),
'April' => Array('num_dates'=>0, 'dates'=>Array()),
'May' => Array('num_dates'=>0, 'dates'=>Array()),
'June' => Array('num_dates'=>0, 'dates'=>Array()),
'July' => Array('num_dates'=>0, 'dates'=>Array()),
'August' => Array('num_dates'=>0, 'dates'=>Array()),
'September' => Array('num_dates'=>0, 'dates'=>Array()),
'October' => Array('num_dates'=>0, 'dates'=>Array()),
'November' => Array('num_dates'=>0, 'dates'=>Array()),
'December' => Array('num_dates'=>0, 'dates'=>Array())
);
$date_arr = Array();
$date_start = "07/05/2013";
$date_arr[] = date('M j, Y', strtotime($date_start));
for ($i=1; $i<=17; $i++){
$date_temp = date('M j, Y', strtotime($date_arr[$i-1] . " + 14 day"));
$month = date('F', strtotime($date_temp));
$month_arr[$month]['dates'][] = $date_temp;
$month_arr[$month]['num_dates'] += 1;
$date_arr[] = $date_temp;
}
foreach ($month_arr as $k => $v){
if (!empty($v)){
if ($v['num_dates'] != 0){
echo "<BR><BR>Month: " . $k;
echo "<BR>No. of dates: " . $v['num_dates'];
foreach ($v['dates'] as $k1=>$v1){
echo "<BR>" . $v1;
}
}
}
}
?>
此时,$ month_arr应该有你需要的一切。
At this point, $month_arr should have everything you need.
