For various scripts, I need the ability to read *all* variables that have
been sent to a .phtml page (for example a Form Email page with unlimited
number of fields). That feature is *really* needed.

$argc should contain the variable count,
$argv[0] ... $argv[$argc - 1] (???)  should contain variable name and
variable content (for example:
 $argv[0] = "FIELD1=Test"
 $argv[1] = "FROM=email@address.com"
etc

or:
 $argv[0] = "FIELD1"
 $argv[1] = "Test"
 $argv[2] = "FROM"
etc.
