What are some common pitfalls to avoid when using loops and conditional statements in PHP to format and display data from a database?

One common pitfall to avoid when using loops and conditional statements in PHP to format and display data from a database is not properly handling empty results. It's important to check if there are any rows returned from the database query before trying to loop through them. Failure to do so can result in errors or unexpected behavior in your application. 

// Check if there are any rows returned from the database query
if ($result->num_rows > 0) {
    // Loop through the rows and display the data
    while ($row = $result->fetch_assoc()) {
        // Display the data here
    }
} else {
    echo "No results found.";
}
