Actuall URL

hyabusa

Hey, is there a way to retrieve an actuall url?, like taking notice of the ..

so if you have

http://www.mysite.com/the/page/is/in/this/../index.htm

would be like

http://www.mysite.com/the/page/is/in/index.htm

Thanks, Craig

I'm not sure what you're trying to do. Can you explain a bit?

Well i have lots of url's in a database im taking them out and some of them are like

http://www.mysite.com/1/2/3/4/../index.html
http://www.hissite.com/1/../2/index.html

they would become

http://www.mysite.com/1/2/3/index.html
http://www.hissite.com/2/index.html

The /../ makes it move back one directory.

Doesn't really matter that much (servers should be able to canonicalise URLs), but I do see why it would be desirable. I thought there was a canonical URL function, but it turns out it was fir filepaths ([man]realpath[/man], as it happens).

So...

$url = preg_replace('![^/]+/\.\./!', '', $url);
$url = str_replace('./', '', $url);

Notice that it assumes that the URL is a sensible one (e.g., http://www.example.com/../silly.html is not sensible).
