[[TestPage?data=Hello%20world]] works -- see
http://www.pmwiki.org/wiki/Test/QueryString . At present
PmWiki doesn't seem to be automatically converting spaces here
into %20, but I think we can get that to work.

Do you mean a page variable (in the markup) or in a PHP script?
In a PHP script one could use either $_GET['data'] or $_REQUEST['data']
to get the value of any variables.
To display the content of a query variable within a page
requires a special markup for it. The Cookbook.HttpVariables
recipe has some markups to support this (among other things).
