What is the common issue with replacing "<br>" with "\n" in PHP textareas?

Replacing "<br>" with "\n" in PHP textareas can cause the line breaks to not display correctly on the frontend because HTML ignores single newline characters. To solve this issue, you can use the PHP function nl2br() when displaying the textarea content. This function converts newline characters into "<br>" tags, ensuring that the line breaks are displayed properly in HTML. 

// Retrieve textarea content with line breaks converted to &quot;&lt;br&gt;&quot; tags
$text_with_br = nl2br($_POST[&#039;textarea_content&#039;]);

// Display the textarea content with correct line breaks
echo $text_with_br;
