PHP strtolower() and strtoupper() Functions

The strtolower() and strtoupper() php functions can be used to change the case of a variable. The example below shows how that is done.

include('connect.inc');
$db = public_db_connect();

$command = "SELECT DISTINCT firstname, lastname, email FROM table_sort WHERE id >0 ORDER BY lastname ASC" ;
$result = mysqli_query($db, $command);
while($row = mysqli_fetch_assoc($result)){
$firstname = strtolower($row['firstname']);
$lastname = strtoupper($row['lastname']);
$email = $row['email'];
echo $firstname."-".$lastname."-".$email."<br/>";
}
