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

Question

I wish to rewrite a mysql query which use month() and year() functions to display all the posts from a certain month which goes to my function as a \'Y-m-d\' parameter forma

Answer 1

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));

Answer 2

cal_days_in_month() should give you the total number of days in the month, and therefore, the last one.

Answer 3

// First date of the current date
echo date('Y-m-d', mktime(0, 0, 0, date('m'), 1, date('Y')));
echo '<br />';
// Last date of the current date
echo date('Y-m-d', mktime(0, 0, 0, date('m')+1, 0, date('Y')));

Answer 4

Print only current month week:

function my_week_range($date) {
    $ts = strtotime($date);
    $start = (date('w', $ts) == 0) ? $ts : strtotime('last sunday', $ts);
    echo $currentWeek = ceil((date("d",strtotime($date)) - date("w",strtotime($date)) - 1) / 7) + 1;
    $start_date = date('Y-m-d', $start);$end_date=date('Y-m-d', strtotime('next saturday', $start));
    if($currentWeek==1)
        {$start_date = date('Y-m-01', strtotime($date));}
    else if($currentWeek==5)
       {$end_date = date('Y-m-t', strtotime($date));}
    else
       {}
    return array($start_date, $end_date );
}

$date_range=list($start_date, $end_date) = my_week_range($new_fdate);

Answer 5

Basically:

$lastDate = date("Y-m-t", strtotime($query_d));

Date t parameter return days number in current month.

Answer 6

$month = 10; // october

$firstday = date('01-' . $month . '-Y');
$lastday = date(date('t', strtotime($firstday)) .'-' . $month . '-Y');
