Assuming register_globals is off:

session_start();
foreach ($HTTP_POST_VARS as $name => $value) {
  $$name = $value;
  session_register($name);
}

Remember, $name only contains the name of the variable, not a
reference to the variable itself.  To create a new global variable
with the name "$name", you have to use a variable variable, hence
$$name.

Session_register, however, only requires a string which contains the
name of the variable you want to register.  $name will provide that by
itself.  In your example, by leaving off the dollar sign, you are
referencing an undefined constant called "name"...

Try putting "" around name in session_register?

I think you're more after this

session_start();
foreach ($HTTP_POST_VARS as $name=>$value) {
$$name=$value;
session_register($name); //with the $
}

Hello, I have captured variables from any HTML that is POSTed to me from a
'foreach' clause. Now, possibly in this foreach clause I want to register
these name/value pairs into a session var. I have tried :
session_start();
foreach ($HTTP_POST_VARS as $name=>$value) {
$name=$value;
session_register(name); //without the $
}
and get nothing.
