日期范围时间查询

Question

I'm trying to query MySQL using a start and end date range. At the moment my variables are:

$begin = $_POST['begin'];
$begin = date('Y/m/d H:i:s', strtotime($begin));
$end = $_POST['end'];
$end = date('Y/m/d H:i:s',strtotime($end));

strtotime($begin) produces an argeeable timestamp '00:00:00'. However I'd like strtotime($end) to output '11:59:59' so that users can query a particular day using the date range in my form. Can someone kindly demonstrate how to set to time as '23:59:59', bearing in mind I wish to use the $end date variable from my form?

My query from PHP is:

"SELECT OrderId, Qty, Del, Timestamp FROM Orders WHERE Timestamp BETWEEN '$begin' AND '$end'";

Many thanks.

Answer 1

strtotime simply produces an integer timestamp, so you could do

$end = date('Y/m/d H:i:s', strtotime($end) + 86400 - 1);

add a day to get "tomorrow", then remove one second to get the moment before midnight of the day you started on.

Or simpler yet:

$end = date('Y/m/d', strtotime($end)) . ' 11:59:59';

produce the appropriate date, then tack on the time portion manually yourself.

如果您想对时间进行硬编码，只需将其连接：

$end = date('Y/m/d', strtotime($end)) . ' 11:59:59';

Answer 3

strtotime returns a timestamp. you can add 86399 (1 day - 1 second)

or you can use the strtotime + syntax so strtotime($end . "+ 23 hours")

or if there is no time info in the variable you can just add it yourself strtotime($end . "+ 23:59")

your other option is to convert to a datetime object which gives much more flexibility
