get startdate and enddate for current quarter php

/*** Compute the start and end date of some fixed o relative quarter in a specific year.* @param mixed $quarter  Integer from 1 to 4 or relative string value:*                        'this', 'current', 'previous', 'first' or 'last'.*                        'this' is equivalent to 'current'.

I develop this function to deal with quarter in any way: relative (this, previous, first, last) and fixed.

Examples:

get_dates_of_quarter();//return current quarter start and end datesget_dates_of_quarter(2);//return 2nd quarter start and end dates of current yearget_dates_of_quarter('first', 2010, 'Y-m-d');//return start='2010-01-01' and end='2014-03-31'get_dates_of_quarter('current', 2009, 'Y-m-d');//Supposing today is '2014-08-22' (3rd quarter), this will return//3rd quarter but of year 2009.//return start='2009-07-01' and end='2009-09-30'get_dates_of_quarter('previous');//Supposing today is '2014-02-18' (1st quarter), this will return//return start='2013-10-01' and end='2013-12-31'

Waiting this help someone ;)

what about:

$offset = (date('n')%3)-1; // modulo ftw$start = new DateTime("first day of -$offset month midnight");$offset = 3-(date('n')%3); // modulo ftw again$end = new DateTime("last day of +$offset month midnight");

Simple code:

$current_quarter = ceil(date('n') / 3);$first_date = date('Y-m-d', strtotime(date('Y') . '-' . (($current_quarter * 3) - 2) . '-1'));$last_date = date('Y-m-t', strtotime(date('Y') . '-' . (($current_quarter * 3)) . '-1'));
