<pedantry> 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> Cheers Chris John Nichel wrote:

I've got a cookie that's either non-existent or a serialized array. I'm trying all sorts of different code combinations to retrieve it into an array variable, but everything I try throws up some combination of notices and/or warnings. Here is my latest & greatest: $cookie = $_COOKIE['bookmarks']; if(unserialize($cookie) == true) {
    $bookmarks = unserialize($cookie);
} else {
    $bookmarks = array();
}
Use isset if ( isset ( $_COOKIE['bookmarks'] ) && unserialize ( $_COOKIE['bookmarks'] ) ) {
    $bookmarks = unserialize ( $_COOKIE['bookmarks'] );
} else {
    $bookmarks = array();
}
