how to get the first and last days of a given month
提问by dole doug
I wish to rewrite a mysql query which use month() and year() functions to display all the posts from a certain month which goes to my function as a 'Y-m-d' parameter format, but I don't know how can I get the last day of the given month date.
我希望重写一个 mysql 查询，该查询使用 month() 和 year() 函数来显示某个月份的所有帖子，这些帖子作为“Ymd”参数格式进入我的函数，但我不知道如何获得给定月份日期的最后一天。
$query_date = '2010-02-04';
list($y, $m, $d) = explode('-', $query_date);
$first_day = $y . '-' . $m . '-01';

I know this question has a good answer with 't', but thought I would add another solution.
我知道这个问题有一个很好的答案 't'，但我想我会添加另一个解决方案。
$first = date("Y-m-d", strtotime("first day of this month"));
$last = date("Y-m-d", strtotime("last day of this month"));

Try this , if you are using PHP 5.3+, in php
试试这个，如果你使用的是 PHP 5.3+，在 php 中
$query_date = '2010-02-04';
$date = new DateTime($query_date);
//First day of month
$date->modify('first day of this month');
$firstday= $date->format('Y-m-d');
//Last day of month
$date->modify('last day of this month');
$lastday= $date->format('Y-m-d');
For finding next month last date, modify as follows,
查找下个月的最后日期，修改如下，
$date->modify('last day of 1 month');
echo $date->format('Y-m-d');
and so on..
等等..

cal_days_in_month()should give you the total number of days in the month, and therefore, the last one.
cal_days_in_month()应该给你当月的总天数，因此，最后一天。

Basically:
基本上：
$lastDate = date("Y-m-t", strtotime($query_d));
Datet parameter return days number in current month.
日期t 参数返回当月的天数。

// First date of the current date
echo date('Y-m-d', mktime(0, 0, 0, date('m'), 1, date('Y')));
echo '<br />';
// Last date of the current date
echo date('Y-m-d', mktime(0, 0, 0, date('m')+1, 0, date('Y')));

$month = 10; // october
$firstday = date('01-' . $month . '-Y');
$lastday = date(date('t', strtotime($firstday)) .'-' . $month . '-Y');

Print only current month week:
仅打印当月周：
function my_week_range($date) {
$ts = strtotime($date);
$start = (date('w', $ts) == 0) ? $ts : strtotime('last sunday', $ts);
echo $currentWeek = ceil((date("d",strtotime($date)) - date("w",strtotime($date)) - 1) / 7) + 1;
$start_date = date('Y-m-d', $start);$end_date=date('Y-m-d', strtotime('next saturday', $start));
if($currentWeek==1)
{$start_date = date('Y-m-01', strtotime($date));}
else if($currentWeek==5)
{$end_date = date('Y-m-t', strtotime($date));}
else
{}
return array($start_date, $end_date );
}
$date_range=list($start_date, $end_date) = my_week_range($new_fdate);
