Question

I searched the millions of similar posts about this but cannot find how to make it count down from 31, 30, 29, 28 etc.

I can have the previous calendar blocks show the 31st but that's all. I need it to show previous month 31st, 30, 29, etc.

updated code from Renku:

    //define the variable dayCol
    $dayCol = 0;

    // Print last months' days spots.
    for ($i=0; $i<$leadInDays; $i++) {

    $lastmonth = date('d', strtotime(-$i.' day', strtotime($startDate))); // Days in previous month

    print "<td width=\"14%\" height=\"25%\" class=\"calendar_cell_disabled_middle\">$lastmonth</td>\n ";

    $dayCol++;
}

example :

Answer 1

I am writing a new loop for this.

 <?php

    $StartDate= date("Y-F-d",strtotime("+0 Month"));// get first day of current month

    $num= 10; // how many past days you need from previous month + 1 (to remove current day)

    for ($i=1; $i<$num; $i++) {

    echo $prev= date('Y-m-d', strtotime(-$i.' day', strtotime($StartDate)))."<br />"; //get last days of previous month

}

    ?>

I am re writing it with your loop,

<?php

$dayCol = 0;

$leadInDays = 5; // (just for February cuz theres 5 blanks before its the 1st of Feb)

$StartDate= date("Y-F-d",strtotime("+0 Month"));

// Print last months' days spots.
for ($i=1; $i<($leadInDays+1); $i++) {

    $lastmonth = date('d', strtotime(-$i.' day', strtotime($StartDate))); // Days in previous month

    print "<td width=\"14%\" height=\"25%\" class=\"calendar_cell_disabled_middle\">$lastmonth</td>\n ";

    $dayCol++;
}
?>

Answer 2

I would use date('t') to get the number of days in said month and just loop backwards:

$month = '2013-02-05';

for($i = date('t', strtotime($month)); $i > 0; $i--) {
  ...
}
