How to add visited pages urls into a session array?

Question

Everytime the user visit a page, the page url will be stored into an array session. I want to have 10 elements in the array only. So that 10 elements will save 10 latest visited

Answer 1

Simplest way to do this and keep just the last 10 entries will be to create your initial array with the correct size (via array_fill()). Then we can push new items onto the beginning of the array and pop old items off the other end using array_unshift() and array_pop().

session_start();

// Initialise URL array with 10 entries.
if (empty($_SESSION['pageurls'])) {
    $_SESSION['pageurls'] = array_fill(0,10,'');
}

function trackPage($url) {
    array_unshift($_SESSION['pageurls'],$url);
    array_pop($_SESSION['pageurls']);
}

Make sure the above code always runs first. Then you can pass new URLs to the array when you want. So, perhaps something like:

trackPage($_SERVER['REQUEST_URI']);
