Using php, how would I make my the background image on my website change based on the current month?? 

January = 01.jpg

Febuary = 02.jpg

etc....

Currently I am using "rotator.php" in a separate directory to get a different image with each refresh. 

css file I have this:

body

{

background: url(../images/theme/backdrop/rotator.php);

which links to the rotator.php obviously.... I wanted to replace the rotator.php with index.php but am not sure what to use for code to get it to call up the images.

This is what I have so far.... 

```
 <?php

 // Image File Ext.

$extList = array();
$extList['gif'] = 'image/gif';
$extList['jpg'] = 'image/jpeg';
$extList['jpeg'] = 'image/jpeg';
$extList['png'] = 'image/png';

//today and Image to use per today

$today = date('m');
printf('$today');

if ($today == 01) {
    $image = "01.jpg";
}
elseif ($today == 02) {
    $image = "02.jpg";
}
elseif ($today == 03) {
    $image = "03.jpg";
}
elseif ($today == 04) {
    $image = "04.jpg";
}
elseif ($today == 05) {
    $image = "05.jpg";
}
elseif ($today == 06) {
    $image = "06.jpg";
}
elseif ($today == 07) {
    $image = "07.jpg";
}
elseif ($today == 08) {
    $image = "08.jpg";
}
elseif ($today == 09) {
    $image = "09.jpg";
}
elseif ($today == 10) {
    $image = "10.jpg";
}
elseif ($today == 11) {
    $image = "11.jpg";
}
elseif($today == 12) {
    $image = "12.jpg";
}

?>

```

Not sure if this is going in the right direction....
