eliminating spaces in url with urlencode

[Anon]

I want to eliminate spaces in my urls. They pop up when sending variables that may contain spaces.

Problem is with urlencode, if I do something like this:

echo "blah" . urlencode("url") . "blah";

then it sticks % codes in for the ? and the = and all that, and my server is not giving me the page.

I could use urlencode only on the non-numeric variables, but this seems kind of messy.

I don't want to just urlencode the variables as they come in, as I need them encoded sometimes, and others not.

I could just use replace to replace blanks with +'s maybe?

What is the best way to do this?

Here:
http://www.php.net/manual/en/function.urlencode.php
it gives you an example on how to use urlencode(). You're not supposed to urlencode() the whole URL, just the stuff after every '='
