Are there any best practices for optimizing PHP code when working with database queries and displaying results in tables?

When working with database queries and displaying results in tables in PHP, it is important to optimize the code for performance. One way to do this is by minimizing the number of queries sent to the database and fetching only the necessary data. Additionally, using proper indexing on the database tables can also help improve query performance. 

// Example of optimizing PHP code for database queries and displaying results in tables
// Connect to the database
$connection = new mysqli('localhost', 'username', 'password', 'database');

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

// Perform a single query to fetch necessary data
$query = "SELECT * FROM table_name WHERE condition = 'value'";
$result = $connection->query($query);

// Display results in a table
echo "<table>";
echo "<tr><th>Column 1</th><th>Column 2</th></tr>";
while ($row = $result->fetch_assoc()) {
    echo "<tr><td>" . $row['column1'] . "</td><td>" . $row['column2'] . "</td></tr>";
}
echo "</table>";

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