[PHP] Creating Dynamic Variables
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.

Re: [PHP] Creating Dynamic Variables
Try putting around name in session_register?

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...
