How can PHP developers ensure that special characters like \n and \t are properly escaped in database entries?

Special characters like \n and \t can be properly escaped in database entries by using PHP's built-in function mysqli_real_escape_string() before inserting the data into the database. This function will escape special characters, preventing SQL injection attacks and ensuring the data is stored correctly in the database. 

// Assuming $db is your database connection
$data = "This is a string with special characters like \n and \t";
$escaped_data = mysqli_real_escape_string($db, $data);

// Now $escaped_data can be safely inserted into the database
$query = "INSERT INTO table_name (column_name) VALUES ('$escaped_data')";
mysqli_query($db, $query);
