What are the best practices for converting newline characters to HTML line breaks for display in a textarea?
When displaying text from a textarea in HTML, newline characters need to be converted to HTML line breaks (<br>) in order to maintain the formatting. One way to achieve this is by using the PHP function nl2br() which automatically converts newline characters to <br> tags. This function can be applied to the text retrieved from the textarea before displaying it on the webpage.
$text_from_textarea = $_POST['textarea_input']; // Retrieve text from textarea
$text_with_linebreaks = nl2br($text_from_textarea); // Convert newline characters to HTML line breaks
echo $text_with_linebreaks; // Display text with line breaks in HTML
