Cookie Problems

[Zimm]

I was trying to figure out how to store an array of data into a single cookie, and by searching these forums I found out how. Although, when I went to test it, I got an error I'm unfamilyar with...

The code is:

<?

if ( $step == NULL ) {
	/* SET COOKIE */
	$setcookie_var1 = "Something";
	$setcookie_var2 = "2.50";
	$setcookie_var3 = "CatA";
	setcookie("testcookie",$setcookie_var1.":".$setcookie_var2.":".$setcookie_var3,(time()+604800),"/","",0);
	print '<p><a href="testcookie.php?step=2">Next step</a>';
}

if ( $step == "2" ) {
	$value_delimiter = ":";
	$the_cookie_mon = $HTTP_COOKIE_VARS["testcookie"];
	$array = explode("$value_delimiter",$the_cookie_mon);
}

?>

The error I get is:

Warning: Cannot add header information - headers already sent by (output started at /usr/local/psa/home/vhosts/codercastle.com/httpdocs/testcookie.php:4) in /usr/local/psa/home/vhosts/codercastle.com/httpdocs/testcookie.php on line 8

Next step

Thanks

you can't output anything that will print something on the page before any cookies are set or unset.

use
ob_start();
on the start of the file

and

ob_end_flush();
at the end of the file

this will buffer the output and u can redirect or do anything because output will be show after encounter
ob_end_flush();
