Are there any potential pitfalls when dealing with line breaks in PHP from HTML textarea?

When dealing with line breaks in PHP from an HTML textarea, one potential pitfall is that line breaks are represented differently in different operating systems (e.g. Windows uses "\r\n" while Unix uses "\n"). To ensure consistent handling of line breaks, you can use the PHP function `nl2br()` to convert newline characters to HTML line breaks ("<br>"). This function will convert all newline characters to "<br>", regardless of the operating system. 

&lt;?php
// Retrieve text from HTML textarea
$text = $_POST[&#039;textarea&#039;];

// Convert newline characters to HTML line breaks
$text_with_line_breaks = nl2br($text);

// Output the text with HTML line breaks
echo $text_with_line_breaks;
?&gt;
