What are the potential pitfalls of not properly handling MySQL result resources in PHP?

If MySQL result resources are not properly handled in PHP, it can lead to memory leaks and performance issues as the resources are not released properly after use. To avoid this, it is important to free up the result resources using the `mysqli_free_result()` function after fetching the data from the result set.

// Fetch data from MySQL database
$result = mysqli_query($connection, "SELECT * FROM table");

// Process the result set
while ($row = mysqli_fetch_assoc($result)) {
    // Do something with the data
}

// Free up the result resources
mysqli_free_result($result);
