Are there any best practices for handling line breaks (\n) in PHP variables before storing them in a database?

When handling line breaks (\n) in PHP variables before storing them in a database, it is important to sanitize the input to prevent SQL injection attacks and ensure data integrity. One common approach is to use the `mysqli_real_escape_string()` function to escape special characters, including line breaks, before inserting the data into the database. 

// Assuming $input contains the user input with line breaks
$escaped_input = mysqli_real_escape_string($connection, $input);

// Insert the sanitized input into the database
$query = "INSERT INTO table_name (column_name) VALUES ('$escaped_input')";
mysqli_query($connection, $query);
