<div class="product-overlay">

<div class="choose">
<ul class="nav nav-pills nav-justified">

Answer 1

You can add the id into a query string, like http://blah.com/product.php?id=123
<a href="../homescreen/product/product.php?id=<?= $product_array[$key]["id"]; ?>" class="btn btn-default add-to-cart">
<i class="fa fa-shopping-cart"></i>Add to cart
</a>
And in your other page,
$id = filter_input(INPUT_GET, 'id', FILTER_SANITIZE_NUMBER_INT);
We do that instead of the dangerous $id = $_GET['id'];. Check the docs for filter_input here http://php.net/manual/en/function.filter-input.php
