What are the potential pitfalls of not using store_result in PHP mysqli when fetching data from a database?

When fetching data from a database using PHP mysqli, not using store_result can lead to potential issues such as increased memory usage and slower performance, especially when dealing with large result sets. By using store_result, the entire result set is fetched from the database and stored in memory, allowing for faster access to the data. 

// Connect to the database
$mysqli = new mysqli("localhost", "username", "password", "database");

// Perform a query
$result = $mysqli->query("SELECT * FROM table");

// Store the result set in memory
$result->store_result();

// Fetch data from the result set
while ($row = $result->fetch_assoc()) {
    // Process the data
}

// Free the result set
$result->free();

// Close the connection
$mysqli->close();
