Need Help Fast: How do I put spaces in a url?

I don't really know how to explain the problem. So I'll give an example: On a youtube video if you click twitter under the share options it will show up as a url with spaces in it, and if you click on it the text will show up in the twitter status bar with the spaces. I need to know how to do this. I thought it had to do with %20 or something but when I try that the "%20" shows up. Can someone please help me out.

 

if you use php you can use :

urldecode  and url encode 

Code (markup):

 

%20 is the default way for a space to be displayed you can altar and edit that with php coding.

 

just urlencode your url and get it like a regular querystring using urldecode
