very simple question

[alan123]

I want to know what is the difference between:
$HTTP_COOKIE_VARS['USERNAME'];
and
$_COOKIE['USERNAME'];

Can I use either one in the php code?

thanks

It has to do with the naming of these superglobal arrays.
In version 4.1.0 the naming scheme changed. Before it used to be $HTTP_POST_VARS and it was abbreviated to $_POST
The same is true for COOKIE, SERVER, etc.

As an addendum to DRJ478's post...

The so-called "long-named" arrays, $HTTP_[POST|GET|COOKIE|SERVER]_VARS, were never superglobal. They were merely global arrays.

The so-called "short-named" arrasy, $_[POST|GET|COOKIE|SERVER], are superglobal. They are available everywhere, even inside user-defined functions. The "long" arrays required the use of the global scoping operator.

With the advent of PHP 5, it is optional whether the "long-named" arrays will even be instantiated. The recommended php.ini file that ships with the PHP 5 source tarball has it turned off.
