[SOLVED] setcookie() not changing value

[iarp]

<?php
if(!isset($_COOKIE['iarp_header_img'])) { 
	setcookie("iarp_header_img", '1', time()+60*60*24*30,"/",".iarp.ca");
	$url = $_SERVER['REQUEST_URI'];
	header("Location: $url");
}
						echo "Before: " . $_COOKIE['iarp_header_img'];

switch ($_COOKIE['iarp_header_img']) {
	case '1':
		setcookie("iarp_header_img", '2', time()+60*60*24*30,"/",".iarp.ca");
		break;
	case '2';
		setcookie("iarp_header_img", '1', time()+60*60*24*30,"/",".iarp.ca");
		break;
}
													echo "After: " . $_COOKIE['iarp_header_img'];

?>

 

further down the page:

 

							<?php 
						switch ($_COOKIE['header_img']) {
							case '1':
								echo '<img src="/themes/gear/images/ico.big/earth.png" alt="Earth"></img>';
								break;
							case '2';
								echo '<img src="/themes/gear/images/ico.big/gear.png" alt="Gear"></img>';
								break;
						}
						?>

 

The image in the second block of code on this post, won't change the image, it stays as 1 all the time.

 

I don't need to reload the page in the first switch case because i'm setting the value to the next # for whenever someone changes the page yet again. Any helps appreciated.

Oh i made a mistake. I changed the cookies name in between getting ready to post this. It's now called 'header_img'. I've changed all the iarp_header_img values.

If I remember correctly, setcookie does not alter the value $_COOKIE.

 

 

(Assuming I remember correctly:)

 

 

setcookie's only responsability is to send the correct header for sending a cookie.  It would be a design flaw, in my opinion for setcookie to alter $_COOKIE since $_COOKIE is data read back from the client's cookie, and simply calling setcookie does not mean that the client will receive/honor a cookie header.

	echo "Before: " . $_COOKIE['header_img'];

switch ($_COOKIE['header_img']) {
	case '1':
		$_COOKIE["header_img"] = '2';
		break;
	case '2';
		$_COOKIE["header_img"] = '1';
		break;
}

echo "After: " . $_COOKIE['header_img'];

 

After reading that, i made a few changes. This time the Before and After echo have the appropriate values but are not keeping the values with each page change.
