How can PHP handle line breaks in textareas submitted in HTML forms?

When a textarea is submitted in an HTML form, line breaks are represented by newline characters (\n). To handle these line breaks in PHP, you can use the nl2br() function to convert the newline characters into <br> tags, which will display the line breaks correctly in the browser. 

&lt;?php
if(isset($_POST[&#039;textarea&#039;])){
    $textarea_content = nl2br($_POST[&#039;textarea&#039;]);
    echo $textarea_content;
}
?&gt;
