How can PHP be used to dynamically display only selected products based on user input in a form?

To dynamically display only selected products based on user input in a form, you can use PHP to handle the form submission, retrieve the user input, and then filter the products based on the criteria specified by the user. This can be achieved by comparing the user input with the product data and displaying only the products that match the criteria. 

<?php
// Sample product data
$products = [
    ['name' => 'Product 1', 'price' => 10],
    ['name' => 'Product 2', 'price' => 20],
    ['name' => 'Product 3', 'price' => 30],
];

if ($_SERVER['REQUEST_METHOD'] === 'POST') {
    $selectedPrice = $_POST['price'];

    foreach ($products as $product) {
        if ($product['price'] <= $selectedPrice) {
            echo $product['name'] . ' - $' . $product['price'] . '<br>';
        }
    }
}
?>

<form method="post">
    <label for="price">Select maximum price:</label>
    <input type="number" name="price" id="price" min="0" step="1">
    <button type="submit">Filter Products</button>
</form>
