What are best practices for processing text input from a textarea in PHP to avoid line break issues?

When processing text input from a textarea in PHP, it's important to handle line breaks properly to avoid formatting issues. One common approach is to use the PHP function nl2br() to convert newline characters to HTML line breaks <br>. This ensures that line breaks are displayed correctly when rendering the text on a webpage. 

// Process text input from a textarea and convert newline characters to HTML line breaks
$text = $_POST[&#039;textarea_input&#039;]; // Assuming textarea input is passed via POST method
$processed_text = nl2br($text);

// Display the processed text with correct line breaks
echo $processed_text;
