How can the use of loops, such as foreach and while, help in efficiently processing and displaying data from a MySQL database in PHP?

Using loops like foreach and while in PHP can help efficiently process and display data from a MySQL database by iterating through the result set and displaying each row of data. This allows for dynamic rendering of data without the need to manually write code for each row. By using loops, you can easily handle varying amounts of data and reduce the amount of repetitive code needed to display information. 

// Connect to MySQL database
$connection = mysqli_connect("localhost", "username", "password", "database");

// Query to fetch data from database
$query = "SELECT * FROM table";
$result = mysqli_query($connection, $query);

// Display data using a while loop
while ($row = mysqli_fetch_assoc($result)) {
    echo "Name: " . $row['name'] . "<br>";
    echo "Age: " . $row['age'] . "<br>";
    // Add more fields as needed
}

// Close database connection
mysqli_close($connection);
