Is storing a complete list of German words where I can be replaced with Ü in a database a practical solution for managing user input in PHP applications?

Storing a complete list of German words where "u" can be replaced with "ü" in a database is not a practical solution for managing user input in PHP applications. Instead, a more efficient approach would be to use PHP's built-in functions like `str_replace()` to dynamically replace characters as needed.

$user_input = "uber";
$corrected_input = str_replace("u", "ü", $user_input);
echo $corrected_input; // Output: über
