Markdown "single page" PHP web application with live preview?

I would like to know if there is a PHP web application, such that

When called with something like http://example.com/index.php?inputfile=mymarkdownfile.txt; it will open the file mymarkdownfile.txt at the same location as index.php on the webserver, and render it as Markdown (i.e., it will convert the Markdown to HTML and serve it)
There will be an "edit" button, which opens a "live preview" Markdown editor (like on StackExchange/StackOverflow sites)
When you're done editing and click on the "save" button, previous version is archived on server (saved as text file mymarkdownfile-timestamp.txt), and the changed version is saved as mymarkdownfile.txt.
If you try to "open" a "nonexisting file" (say, via http://example.com/index.php?inputfile=nonexistant.txt), then the editor starts first; and the content typed there will be saved as nonexistant.txt (and nonexistant-timestamp.txt)

I just need this for server based note taking, and I don't really need local linking or anything like that; nor user authentication nor protection (I'd intend to use this on local network, so I wouldn't be worried about public exposure of "edit" button and vandalism).

I imagine it could be a PHP page, which uses:

PHP Markdown library for the initial conversion to HTML when the page request is first read
pagedown - A JavaScript Markdown converter and editor (see also Is there any good Markdown Javascript library or control? - Stack Overflow) for when the editor is active..

Anything like that out there?

Many thanks in advance for any answers,
Cheers!

Well, given that I really needed something like this, I put together a small PHP script/application that does the above; called it the Single-page Markdown Web Editor (spmdwe); please see:

Hope this helps someone,
Cheers!

I'm trying to login into sitejot and I get the error

Fatal error: Maximum execution time of 50 seconds exceeded
 in /home/sitejot/public_html/login.php on line 23

It only happens on one pc, all other pc's at my house do not encounter this error
It happens consistently every time regardless of browser - IE, Firefox, Chrome
I can move the pc to be behind another router and the error remains
It is particular to this web page, other pages in the same web site are ok, and I don't have any problems with any other web pages
Googling "Fatal error: Maximum execution time of 50 seconds exceeded" returns a huge number of hits, so this seems to be a common problem
I've upgraded my pc to Windows 7 with no improvement

Here is the POST request:

There's is no response and eventually it times out. Here is the response header:

What can I try to fix this issue?
