What are the benefits of using nl2br() over manually replacing "\n" with "<br>" in PHP when dealing with user-generated content containing line breaks?

When dealing with user-generated content containing line breaks in PHP, using nl2br() is beneficial over manually replacing "\n" with "<br>" because nl2br() is a built-in function that specifically converts newline characters to HTML line breaks. This ensures consistent formatting across different platforms and avoids potential errors that may arise from manual replacements. Additionally, nl2br() simplifies the code and improves readability.

$userInput = "Hello\nWorld!";
$formattedContent = nl2br($userInput);
echo $formattedContent;
