How can PHP settings affect the search results for names with different letter cases?

PHP settings can affect the search results for names with different letter cases because PHP is case-sensitive by default. To ensure that search results are not affected by letter case, you can use functions like strtolower() or strtoupper() to normalize the input data before performing the search. 

// Example code snippet to normalize input data before performing a search
$searchName = strtolower($_GET['searchName']); // Convert input to lowercase
$result = mysqli_query($connection, "SELECT * FROM users WHERE LOWER(name) = '$searchName'");
