Get the beginning and ending unix timestamp for a given month and year in php (3 answers)

Closed 8 years ago.

I am making a script in which I require views to displayed in today, yesterday, last month, this month. I was able to get views for today and yesterday using the following code:

$hour = 12;

$today_count = strtotime("$hour:00:00");
$yest_count = strtotime('-1 day', $today_count);

My timestamp in database is unix timestamp . How can i achieve to get this month and last month views?

Answer 1

The unix timestamp started on 1 January 1970 and counts the seconds since then. To get the time stamp from 7 days ago you need to know how many seconds that is. eg.

7(days)*24(hours)60(min)(60 sec) = 604,800

From there you can subtract that from the current timestamp.

time() - 604,800 = time stamp from 7 days ago.

This method will work for any time in the past up until 1 January 1970. Once that is done you can convert that timestamp into any date formate you need.
