How to wrap each new line in textarea with li tags? PHP

Question

I have a textarea form field where users will put URL's separated by a new line. Would it be possible to wrap each line from this textarea field with < li > tags?

So I would need the output from the field to be something like this:

<li>some.url.com</li>
<li>some.url.com</li>
<li>some.url.com</li>
<li>some.url.com</li>
<li>some.url.com</li>

Does anyone know who to achive this with PHP please?

Answer 1

$textareaData = '<li>'.str_replace("\n","</li>\n<li>",trim($textareaData,"\n")).'</li>';

EDIT

Modified to get rid of all blank lines as well:

$textareaData = '<li>'.str_replace(array("\r","\n\n","\n"),array('',"\n","</li>\n<li>"),trim($textareaData,"\n\r")).'</li>';
