if register_globals is ON then the variables are already set by php (which,
BTW, can cause all kinds of unexpected grief when html tag names end up as
php vars).

You can test the results by doing this:
<?php
if (!empty($_GET)) { # can't use !empty($_REQUEST) as it always has
something
echo "before foreach a=".$a.",b=".$b.",c=".$c."<br />"; // if
register_globals is on these are already set

# if register_globals is OFF this will set all request vars
foreach ($_REQUEST as $key => $value){
$$key = $value;
}
echo "after foreach a=".$a.",b=".$b.",c=".$c."<br />";
}
else {

echo <<<FORM
<form method="get" action="{$_SERVER['PHP_SELF']}">
<input type="text" name="a" />
<input type="text" name="b" />
<input type="text" name="c" />
<input type="submit" />
</form>
FORM;
}
?>


but be aware that $_REQUEST has extra stuff in it.
