PHP Practical Slip 14 Q.B

Write a PHP script to accept product number from the user. Update the price of the
product and display an appropriate message.

<?php
// Sample product list (associative array: product_number => price)
$products = [
    101 => 50,
    102 => 75,
    103 => 100,
    104 => 120
];

// Initialize message
$message = "";

if ($_SERVER["REQUEST_METHOD"] == "POST") {
    $productNumber = $_POST['product_number'];
    $newPrice = $_POST['new_price'];

    // Check if product exists
    if (array_key_exists($productNumber, $products)) {
        $products[$productNumber] = $newPrice; // Update price
        $message = "Product #$productNumber price updated to $$newPrice successfully.";
    } else {
        $message = "Product #$productNumber not found!";
    }
}
?>

<!DOCTYPE html>
<html>
<head>
    <title>Update Product Price</title>
</head>
<body>
    <h2>Update Product Price</h2>
    
    <form method="post">
        Product Number: <input type="number" name="product_number" required><br><br>
        New Price: <input type="number" name="new_price" step="0.01" required><br><br>
        <input type="submit" value="Update Price">
    </form>

    <?php
    if (!empty($message)) {
        echo "<h3>$message</h3>";
    }
    ?>
</body>
</html>
