Answer 1

Use PHP DOM to parse and add
in it. Like this:

$html = ' put returns between paragraphs
for linebreak add 2 spaces at end
indent code by 4 spaces
quote by placing > at start of line
';

//parsing begins here:
$doc = new DOMDocument();
@$doc->loadHTML($html);
$nodes = $doc->getElementsByTagName('textarea');

//get text and add 
 then remove last 

$lines = $nodes->item(0)->nodeValue;

//split it by newlines
$lines = explode("\n", $lines);

//add 
 at end of each line
foreach($lines as $line)
    $output .= $line . "
";

//remove last 

$output = rtrim($output, "
");

//display it
var_dump($output);

This outputs:

string ' put returns between paragraphs

for linebreak add 2 spaces at end

indent code by 4 spaces

quote by placing > at start of line
' (length=141)
