How can PHP be used to process multiple selections in a MySQL database?

When processing multiple selections in a MySQL database using PHP, you can use a loop to iterate through the selected values and perform the necessary actions on each one. This can be achieved by fetching the selected data from the database, looping through the results, and executing the desired operations for each row. 

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

// Select data from MySQL database
$query = "SELECT * FROM table";
$result = mysqli_query($connection, $query);

// Process multiple selections
if (mysqli_num_rows($result) > 0) {
    while ($row = mysqli_fetch_assoc($result)) {
        // Perform actions on each selected row
        echo "Processing row with ID: " . $row['id'] . "<br>";
    }
} else {
    echo "No rows found in the database.";
}

// Close database connection
mysqli_close($connection);
