Detect line break in textfield

Does anyone know how to detect line break in textfield (without html editor) and convert to paragraph? Thanks in advance!

 

<?
function lb2pg( $data )
{
	$return = null;
	$array = split("\n", $data );
	foreach( $array as $paragraph )
	{
		$return .= "<p>$paragraph</p>\n";
	}
	return $return;
}
echo lb2pg("Hello my name is joe\nI am from the uk\nI live in a house, not a box\nI walk with legs and not wheels");

PHP:

something like that .....

 

Thank you so much ,krakjoe.

 

if you are using php then use nl2br function to replace null with br tags.

 

technoguy: I think you mean replace new lines (not nulls) with br tags...
