How can properly formatting PHP and SQL code improve readability and prevent errors?

Properly formatting PHP and SQL code can improve readability by making the code structure more organized and easier to follow. It can also prevent errors by ensuring that the code is correctly written and formatted according to best practices. By using indentation, comments, and consistent naming conventions, developers can easily understand the code and identify any potential issues. 

<?php

// Example of properly formatted PHP code
$query = "SELECT * FROM users WHERE id = 1";
$result = mysqli_query($connection, $query);

if ($result) {
    while ($row = mysqli_fetch_assoc($result)) {
        echo "Name: " . $row['name'] . "<br>";
    }
} else {
    echo "Error: " . mysqli_error($connection);
}

?>
