What are some potential pitfalls of using replace() to handle line breaks in PHP?

Using replace() to handle line breaks in PHP can be problematic because it may not work consistently across different operating systems (e.g. Windows, Unix). Instead, it is recommended to use PHP's built-in function, nl2br(), which converts newline characters to HTML line breaks. This ensures compatibility and consistency when dealing with line breaks in PHP.

// Using nl2br() to handle line breaks
$text = "Hello\nWorld!";
echo nl2br($text);
