Cookie based recently viewed pages script

How can I make this script to show the title of an ad instead of showing the title of a page? Right now it simply grabs whatever is between <title></title>.

An ad's title is echoed like this <?php echo $adtitle; ?>. Obviously it's in php, but I am wondering if you, guys, somehow can integrate it into the script so that it would show an ad's title instead of the stuff between <title></title>.

By the way I am mostly talking about the HistoryTitle. I want this to grab and remember the recently visited ads' titles. That link[1] is what the title is between <title></title>. I want it to display $adtitle instead.

if( cookiecontent.length < 3 ) { return; }
cookiecontent = unescape(cookiecontent);
var historyList = cookiecontent.split('&');
for( var i = 0; i < historyList.length; i++ ) {
var link = historyList[i].split('=',2);
HistoryLink.push(link[0]);
HistoryTitle.push(link[1]);
var temparray = link[0].split('~amp;');
link[0] = temparray.join('&');
temparray = link[1].split('~amp;');
link[1] = temparray.join('&');
HistoryContent += '<'+'p>'+'<'+'a href="'+link[0]+'">'+link[1]+'<'+'/'+'a>'+'<'+'/'+'p>';
}
}

Can you show what the ad's html code is?
