Are there best practices for handling line breaks in PHP form data to ensure they are stored as "\r\n" and not "rn"?

When handling form data in PHP, line breaks can sometimes be stored as "rn" instead of the desired "\r\n". To ensure line breaks are stored correctly, you can use the PHP function `nl2br()` to convert line breaks to HTML `<br>` tags before storing the data. This will preserve the line breaks as "\r\n" when displaying the data.

// Assuming $formData contains the form data with potential line breaks
$formData = nl2br($formData);

// Store $formData in the database or wherever needed
