我怎样才能获得本月最后一天的时间戳？ [重复]

Question

This question already has an answer here:

• Timestamps of start and end of month 6 answers

I have the current unix timestamp stored in variable $current_time. Using this variable, I want to find out exactly what the timestamp is for the very last day of the current month.

How can I do this in PHP 5.4+?

Here's a working example:

// this is if your $current_time is not within the current month (although the code below is valid for every single month and every single timestamp)
$month = date("M", $current_time);

$last_day_timestamp = strtotime('last day of ' . $month);

echo date("d-m-Y", $last_day_timestamp);

// if your $current_time is within the current month
$last_day_timestamp_of_this_month = strtotime('last day of this month')

Also you could use this as a reference for other relative date/time formats: http://php.net/manual/en/datetime.formats.relative.php
