What are the potential pitfalls of not using a database for managing location, age group, and price data in PHP?

Without using a database for managing location, age group, and price data in PHP, the potential pitfalls include limited scalability, increased complexity in data management, and decreased efficiency in data retrieval and manipulation. To solve this issue, consider using a database management system like MySQL to store and organize the data efficiently. 

// Example of connecting to a MySQL database and querying location, age group, and price data

// Connect to MySQL database
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "database_name";

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

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

// Query data from database
$sql = "SELECT location, age_group, price FROM data_table";
$result = $conn->query($sql);

if ($result->num_rows > 0) {
    // Output data of each row
    while($row = $result->fetch_assoc()) {
        echo "Location: " . $row["location"]. " - Age Group: " . $row["age_group"]. " - Price: " . $row["price"]. "<br>";
    }
} else {
    echo "0 results";
}

$conn->close();
