What are potential pitfalls of using arrays in PHP for storing product data in a shopping system?

One potential pitfall of using arrays in PHP for storing product data in a shopping system is that it can become difficult to manage and scale as the number of products grows. To solve this issue, consider using a database to store product data instead. This will provide better organization, search capabilities, and scalability for your shopping system. 

// Example of storing product data in a database table
// Create a products table in your database with columns for product_id, name, price, etc.

// Connect to the database
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "shopping_system";

$conn = new mysqli($servername, $username, $password, $dbname);

// Check connection
if ($conn->connect_error) {
    die("Connection failed: " . $conn->connect_error);
}

// Query to retrieve product data from the database
$sql = "SELECT * FROM products";
$result = $conn->query($sql);

if ($result->num_rows > 0) {
    // Output data of each row
    while($row = $result->fetch_assoc()) {
        echo "Product ID: " . $row["product_id"]. " - Name: " . $row["name"]. " - Price: " . $row["price"]. "<br>";
    }
} else {
    echo "0 results";
}

$conn->close();
