No Eddie, it's one of the beautiful, simple and powerful things about
PHP.
http://www.php.net/manual/en/language.variables.variable.php
As I loop over the hash, i am TRYING to create a new class property of
the key and assigning it the value.
$pkey is basically the hash's $key in mixed case, forced to lowercase.
You can do this for variables and for functions/methods too. This is a
'factory'. I've used it for example for parsing an XML file and
operating on the data within various 'blocks' by reading the <block
name="foo" value="bar"> and then executing $$name($value).
Thanks for trying though. ;-)
