How can the use of conditional statements in PHP improve the handling of database queries and result processing?

Using conditional statements in PHP can improve the handling of database queries and result processing by allowing you to check for specific conditions before executing certain actions. For example, you can use conditional statements to check if a query was successful before proceeding to process the results. This can help prevent errors and ensure that your code behaves as expected. 

// Example of using conditional statements to handle database queries and results

// Execute a query
$query = "SELECT * FROM users WHERE id = 1";
$result = mysqli_query($connection, $query);

// Check if the query was successful
if($result) {
    // Process the results
    while($row = mysqli_fetch_assoc($result)) {
        echo "User ID: " . $row['id'] . " - Name: " . $row['name'] . "<br>";
    }
} else {
    echo "Error: Unable to retrieve user data.";
}
