Hello,
The following is a code excerpt I found on the web. Could someone please tell me where I can find information about how to use $$ variables and ${$var} variables. I have never seen them before.
foreach ($expected as $formvar)
$$formvar = (isset(${"_$_SERVER[REQUEST_METHOD]"}[$formvar]))?
${"_$_SERVER[REQUEST_METHOD]"}[$formvar]:NULL;

I don't prefer using this because its too difficult to keep track of what is in $var. If something goes wrong in the script, for example, $var is empty, then that will cause a total failure.
