$handler = new Lablnet\DSHandler();

Remove array/products by key:value
//remove array by key:value
$handler->_remove($products, 'rating', 2.9);
echo "<h3>Remove array by key:value</h3><pre>";
print_r($products);
echo "</pre>";
echo "<br>";

Remove duplicate array by key
//remove duplicate array by key
$unique = $handler->_unique($products, 'name');
echo "<h3>Remove duplicate value by key</h3><pre>";
print_r($unique);
echo "</pre>";
echo "<br>";

Sort the products base on price
//Now sort the products base on price
$sort_1_price = $products;
$handler->_sort($sort_1_price, 'price', SORT_ASC);
echo "<h3>Sort by price ASC</h3><pre>";
print_r($sort_1_price);
echo "</pre>";
echo "<br>";
$sort_2_price = $products;
$handler->_sort($sort_2_price, 'price', SORT_DESC);
echo "<h3>Sort by price DESC</h3><pre>";
print_r($sort_2_price);
echo "</pre>";
echo "<br>";

Sort the products based on rating

$sort_1_rating = $products;
$handler->_sort($sort_1_rating, 'rating', SORT_ASC);
echo "<h3>Sort by Rating ASC</h3><pre>";
print_r($sort_1_rating);
echo "</pre>";

$sort_2_rating = $products;
$handler->_sort($sort_2_rating, 'rating', SORT_DESC);
echo "<h3>Sort by Rating DESC</h3><pre>";
print_r($sort_2_rating);
echo "</pre>";
echo "<br>";
