Reverse whole date in php

NaeemX2

OK,

i was using following code to reverse a date to use in php yesterday.

<?php
$d=date("F j Y");
$d=explode(" ", $d);
$month=$d[0];
$day=$d[1];
$year=$d[2];
<?php for ($i=10; $i>0; $i--)
{
      $date=$month."-".$day--."-".$year;
      echo $date;
?>

this was working for me till yesterday 31 March Night. but in the morning on april 1 its started printing

April-1-2012

April-0-2012

April–1-2012 April–2-2012

and so on.

this was the bad logic i used to reverse a date. i realized it soon.
i want this like following.

April-1-2012

March-31-2012

March-30-2012

March-29-2012

and so on

so how this could be possible ?

Thanks in advance.

Well, this also a logic that work perfect for me i made after post of question. but i am really thankful for all answers. that also making me many things clear.

<?php
$d=date("F j Y");
 for ($i=0; $i>-10; $i--)
 {
$date="<br>".date('F-j-Y', strtotime("+$i days"));
echo $date;
}
?>
