Form data can be passed by $HTTP_POST_VARS to a function or another form and then quickly
reinitialze data
<input type=text name=email>
<input type=text name=firstname>
.
.
.
When submitted you can usually reference the variable by name ie:
<?
if($email)
?>
but if you have a long list of variables you want recreated or passed to a function you can do the
following:
<?
foreach($HTTP_POST_VARS as $keys=>$values){
${$keys}=$values;
}
?>
it's like saying
<?
$email=$HTTP_POST_VARS['email'];
?>
for all values within the HTTP_POST_VAR array
<?
function foo($HTTP_POST_VARS){
foreach($HTTP_POST_VARS as $keys=>$values){
${$keys}=$values;
}
if($email=someone@somewhere.com){
//do something
}
}
?>
now instead of doing this
<?
$email=$HTTP_POST_VARS['email'];
$firstname=$HTTP_POST_VARS['firstname'];
?>
all the values are initialized and can be used with out renaming or reseting them |

You can also do it this way
extract($_POST);
one line, nice and easy.
And, using the Super Gloabl arrays ($_GET, $_POST etc etc) you have access to the variables anywhere - they are global in scope.
RTM to confirm the details on both...
