Re: Grab an array from a cookie without throwing errors?

Of course, you're running unserialize() twice.

What about

if (empty($_COOKIE['bookmarks']) || !($bookmarks = 
unserialize($_COOKIE['bookmarks'])))
{
 $bookmarks = array();
}

Does the same with only one call to a potentially weighty function.

</pedantry>
