Show HN: Source small php page that shows the public source code of a Web page (opens in new tab)

Hi guys, I did this little self contained script in a little over a week to enhance my php knowledge.

Some problems I've found are: redirects and non 200 status codes.

I plan on redoing the whole thing in JavaScript or any other client side technology and add color coding.

PHP already has a filter (FILTER_VALIDATE_URL) for validating urls using filter_var[0], however, it doesn't work on international URLs. You can also break up a url with parse_url()[1]

You might also want to look into PHP's curl wrapper which is a lot more powerful[2].
