How to treat single newline as real line break in PHP Markdown?

[siirderyasi]

I was reading http://github.github.com/github-flavored-markdown/ I would like to implement that "Newline modification" in PHP Markdown:Best I could think of is: \[code\]$my_html = Markdown($my_text);$my_html = preg_replace("/\n{1}/", "<br/>", $my_html);\[/code\]But this runs very unexpectable.
