What are common challenges faced when trying to create line breaks in PHP input fields?

When trying to create line breaks in PHP input fields, one common challenge is that HTML line breaks (br tags) are not rendered properly in textareas. To solve this issue, you can use the PHP nl2br function to convert newline characters (\n) into HTML line breaks. 

<?php
$input_text = "This is a text with\nline breaks.";
$formatted_text = nl2br($input_text);

echo "<textarea>$formatted_text</textarea>";
?>
