Parsing Data from URL's containing colon character

I'm using PHP Simple HTML DOM Parser to grab some data form wikipedia.

it uses a file_get_contents function to load the URLs.

I'm getting a 403 forbidden error on line 39 from URLs containing the " : " character.

I've attempted to replace the colon with %3A to no avail

Any help would be appreciated

Cheers,

Georges

Can you be more specific and provide examples of URL's that work and don't work
