Unique entries in an array

Question

I have the following that stores the previous 10 URL\'s into a session:

function curPageURL() {
 $pageURL = \'http\';
 if ($_SERVER[\"HTTPS\"] == \"on\") {$pageU         


        

Answer 1

instead of $_SESSION['pages'][] = $CurrentPage try $_SESSION['pages'][$CurrentPage] = 1

/edit: to keep items sorted, unset first:

 unset($_SESSION['pages'][$CurrentPage]);
 $_SESSION['pages'][$CurrentPage] = 1;
