Removing unnecessary dots in a URL with preg_replace

Let's say somebody post URLs that look like this:


http:/ /something.com.
http:/ /something.org.
http:/ /something.info.

or like this:

http:/ /something.com...
http:/ /something.org...
http:/ /something.info...

or like this:

...http:/ /something.com
...http:/ /something.org
...http:/ /something.info

Is there a way to clean up URLs from any dots that are not supposed to be there?

Any input will be appreciated.

 

You can use the trim function: $url = trim($url, '.');

 

Thanks, ThePHPMaster.

Here's what I am using. Was poking around and came upon this somewhere:

$text = preg_replace( '/(\b)(http|ftp|https|mailto)([\:\/\/])([A-z0-9~!@$%&*()_+:?,.\/;=#-]{2,}[A-z0-9~@$%&*_+\/=])/', " $2$3$4 ", $text);

Code (markup):

I decided to simply put a space on each end of a link, instead of trying to strip all / any characters that may come in contact with it (which in my case used to interfere with a link's accuracy).

It's not perfect, it won't work with domain names ending in .com.de or .org.uk, etc. but other than that I am pretty happy with it.


Thanks for the suggestion.
