Change image based on time of day

Was wondering if anyone had a quick and dirty way to change a image based on time of day. I have a image that we have a dark and light version of that we use in the top left corner of our site. We would like to have it change based on night and day.

in your header include

Php Code:


<?php
$t = getdate();
$hr = $t['hours'];
if ($hr > 12) { ?>
<img src="http://yoursite.com/path/to/image/beforenoon.jpg" />
<?php } else { ?>
<img src="http://yoursite.com/path/to/image/afternoon.jpg" />
<?php } ?>

for example

or

Php Code:


<?php
$t = getdate();
$hr = $t['hours'];
if ($hr > 12) {
echo '<img src="http://yoursite.com/path/to/image/beforenoon.jpg" />';
} else {
echo '<img src="http://yoursite.com/path/to/image/afternoon.jpg" />';
} 
?>

If you were using SD's second block of code - you would simply drop the entire string that you posted into this bit...

Code:

echo '';

...although I would have thought that if $hr > 12 it would be the afternoon period.

Is that right SD?

So I would just replace the line I have in the middle of other code with the <?php....

Yes, the main page is php enabled (ubbthreads.php), so you just need the <?php and ?> tags to tell the php engine to do its thing.

(As opposed to just parsing regular text or HTML.)

I just popped SDs code into my default header and it worked just fine...

Php Code:



<?php
$t = getdate();
$hr = $t['hours'];
if ($hr > 12) {
echo 'night';
} else {
echo 'day';
} 
?>
