Converting plain text into html paragraphs

[knightmetal]

I'm trying to write a function that converts plain text into paragraphs wrapped around <p> tags. Here's an input/output example:

Input:

$text = <<< OUT
Paragraph 1

Paragraph 2

Paragraph 3
OUT;

Output:
$text = <<< OUT
<p>Paragraph 1</p>
<p>Paragraph 2</p>
<p>Paragraph 3</p>
OUT;

Can anyone give me a helping hand? Thanks a lot.

PHP Code:

<?php
//Input:

$text = "<<< OUT
Paragraph 1

Paragraph 2

Paragraph 3
OUT;";

function P_Convertor($input){
    $output = '';
    $lines = explode("\n\r",$input);
    foreach ($lines as $k => $v){
        $output .= "<p>".str_replace("\n\r", "", $v)."</p>".PHP_EOL;
    }
    return $output;
}

$test = P_Convertor($text);
echo $test;
?>
