How can the encoding of data in the database affect the display of special characters like ä,ö,ü in PHP?

Special characters like ä,ö,ü can be affected by the encoding of data in the database. To ensure these characters display correctly in PHP, make sure that the database encoding matches the PHP encoding. You can set the character set in PHP using the mysqli_set_charset() function to match the database encoding. 

<?php
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "database";

$conn = new mysqli($servername, $username, $password, $dbname);

// Set the character set to match the database encoding
mysqli_set_charset($conn, "utf8");

// Rest of your PHP code here
?>
