Making a url with timestamp, whitespace between date and time breaks url

Question

I'm working on the Head First PHP and MySql book, and I have this problem with a date/timestamp. I'm going to make an URL with a date as a GET parameter. But when the date is returned from the database (type of timestamp), there is a white space betwen the date and the time, so the URL breaks.

How can I format the date to get included in the URL (along with the rest of the parameters)?

Answer 1
