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

[Chris Dowell]

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.

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();
}
