How to Find the First and Last Date in a Month Using PHP

How can I find the first and last date in a month using PHP?

The easiest way is to use date, which lets you mix hard-coded values with ones extracted from a timestamp. If you don't give a timestamp, it assumes the current date and time.

// Current timestamp is assumed, so these find first and last day of THIS month
$first_day_this_month = date('m-01-Y'); // hard-coded '01' for first day
$last_day_this_month  = date('m-t-Y');

// With timestamp, this gets last day of April 2010
$last_day_april_2010 = date('m-t-Y', strtotime('April 21, 2010'));

date() searches the string it's given, like 'm-t-Y', for specific symbols, and it replaces them with values from its timestamp. So we can use those symbols to extract the values and formatting that we want from the timestamp. In the examples above:

• Y gives you the 4-digit year from the timestamp ('2010')
• m gives you the numeric month from the timestamp, with a leading zero ('04')
• t gives you the number of days in the timestamp's month ('30')

You can be creative with this. For example, to get the first and last second of a month:

$timestamp    = strtotime('February 2012');
$first_second = date('m-01-Y 00:00:00', $timestamp);
$last_second  = date('m-t-Y 12:59:59', $timestamp); // A leap year!

See http://php.net/manual/en/function.date.php for other symbols and more details.

How to find the last day of the month from date?

t returns the number of days in the month of a given date (see the docs for date):

$a_date = "2009-11-23";
echo date("Y-m-t", strtotime($a_date));

how to get the first and last days of a given month

You might want to look at the strtotime and date functions.

<?php

$query_date = '2010-02-04';

// First day of the month.
echo date('Y-m-01', strtotime($query_date));

// Last day of the month.
echo date('Y-m-t', strtotime($query_date));

The best way to get the first and last day of last month?

In PHP 5.3, you can use the DateTime class :

<?php

$month_ini = new DateTime("first day of last month");
$month_end = new DateTime("last day of last month");

echo $month_ini->format('Y-m-d'); // 2012-02-01
echo $month_end->format('Y-m-d'); // 2012-02-29

Getting first day of a given month in PHP?

The strtotime function supports relative time formats. You can just do this instead:

$date = strtotime('20140702');
$first_date = strtotime('first day of this month', $date);
$first_day_of_month = date('w', $first_date);

The second parameter to strtotime provides the time that the relative format will be relative to. You can use this to easily calculate dates relative to a particular point, as shown above.
