将日期转换为时间戳[重复]

Okay so basically I have two variables one called $day and another called $time what I'm trying to do is convert both of these into a unix time-stamp so for example;

$day = 'Monday';
$time = '14:00:00';

So what I'm looking for is a $timestamp variable that would echo out the next Monday coming up at 14:00:00 in a unix timestamp format.

I'm guessing the hardest part of this would be the fact that the day is not a specific date more a day of the week meaning it would have to select the next monday coming up, or the next tuesday... for example.

Thanks for any help.

The constructor for the DateTime class is pretty good at figuring this sort of thing out:

<?php
$day = 'Monday';
$time = '14:00:00';

$date = new DateTime("next $day $time");
echo $date->getTimestamp();
// 1475503200

$datetime = new DateTime();
echo $datetime->format('U');

Solution One:

mktime - Get Unix timestamp for a date

echo mktime(23, 24, 0, 11, 3, 2009);
1257290640

Returns the Unix timestamp corresponding to the arguments given. This timestamp is a long integer containing the number of seconds between the Unix Epoch (January 1 1970 00:00:00 GMT) and the time specified.

Arguments may be left out in order from right to left; any arguments thus omitted will be set to the current value according to the local date and time.

mktime($isAM ? $hrs : ($hrs + 12), $mins, $secs, $m, $d, $y);

To handle AM/PM just add 12 to hours if PM.

Solution Two:

strtotime Returns a timestamp on success, FALSE otherwise.

echo strtotime('2012-07-25 14:35:08' );

Output:

1343219708
