How can server configurations impact the functionality of PHP functions like mysqli_real_escape_string()?

Server configurations can impact the functionality of PHP functions like mysqli_real_escape_string() by affecting the connection to the database or the character set used for encoding. To ensure proper functionality, it is important to set the correct character set and establish a secure connection to the database. 

// Establish a connection to the database with the correct character set
$connection = mysqli_connect("localhost", "username", "password", "database");
mysqli_set_charset($connection, "utf8");

// Use mysqli_real_escape_string() function on user input
$user_input = "user's input";
$escaped_input = mysqli_real_escape_string($connection, $user_input);

// Perform database query with the escaped input
$query = "INSERT INTO table_name (column_name) VALUES ('$escaped_input')";
mysqli_query($connection, $query);

// Close the database connection
mysqli_close($connection);
