alternative way get the last day of the month

This is more flexible that the above methods, because you don't need to check the date. Everything will be dynamic adjust to the date and year accordingly.

<?php
   $month = date('m')-2;
   $last_day_of_last_month = date('Y-m-t', mktime(0,0,0,$month,1,2012));
   echo $last_day_of_last_month;
?>

get the date range for previous month

• This is not the best method, but it is working.

<?php

$current_month = intval(date('m'));
$year = date('Y');
$last_month = null;

if ($current_month == 1) {
    $last_month = 12;
    $year = intval($year - 1);
} else {
    $last_month = intval($current_month - 1);
}


$mydate = strtotime("$year-$last_month-01");
$day = date('t', $mydate);

$first_date_of_month = "{$year}-{$last_month}-1";
$laste_date_of_month = "{$year}-{$last_month}-{$day}";

echo $first_date_of_month . '<br/>';
echo $laste_date_of_month . '<br/>';
?>
