strtotime

Synopsis

int strtotime(string time[, int timestamp])

Converts an English description of a time and date into a Unix timestamp value. Optionally, a timestamp can be given that the function uses as the “now” value; if not, the current date and time is used.

The descriptive string can be in a number of formats. For example, all of the following will work:

echo strtotime("now");
echo strtotime("+1 week");
echo strtotime("-1 week 2 days 4 seconds");
echo strtotime("2 January 1972");
