How can binary marking in MySQL fields impact search results for names with varying letter cases?

Binary marking in MySQL fields can impact search results for names with varying letter cases because MySQL by default is case-insensitive when comparing strings. To ensure case-sensitive searches, you can use the BINARY keyword in your SQL queries to mark specific fields as binary, thus making the comparisons case-sensitive. 

// Assuming $name is the input name to search for
$name = 'John Doe';

// Using the BINARY keyword in the SQL query to make the comparison case-sensitive
$query = "SELECT * FROM users WHERE BINARY name = '$name'";
$result = mysqli_query($connection, $query);

// Fetching and displaying the results
while ($row = mysqli_fetch_assoc($result)) {
    echo $row['name'] . "<br>";
}
