The note above says:

"Also see the import_request_variables() function. "

But dont:

This function has been DEPRECATED as of PHP 5.3.0 and REMOVED as of PHP 5.4.0.

Just a reminder about security: the chosen HTTP request verb (e.g. POST, GET) does not necessarily make the request "secure". Any information that is not transmitted over an encrypted channel (using SSL, i.e. HTTPS) is transmitted in plan text.

For secure transport of sensitive/private information over HTTP consider using SSL as this prevents eve's dropping of the information transmitted over HTTP.

Also, don't ever use GET method in a form that capture passwords and other things that are meant to be hidden.

[Editor's Note: Since "." is not legal variable name PHP will translate the dot to underscore, i.e. "name.x" will become "name_x"]

Be careful, when using and processing forms which contains

tag. Do not use in your scripts this elements attributes `name` and `value`, because MSIE and Opera do not send them to server.

Both are sending `name.x` and `name.y` coordiante variables to a server, so better use them.

According to the HTTP specification, you should use the POST method when you're using the form to change the state of something on the server end. For example, if a page has a form to allow users to add their own comments, like this page here, the form should use POST. If you click "Reload" or "Refresh" on a page that you reached through a POST, it's almost always an error -- you shouldn't be posting the same comment twice -- which is why these pages aren't bookmarked or cached.

You should use the GET method when your form is, well, getting something off the server and not actually changing anything. For example, the form for a search engine should use GET, since searching a Web site should not be changing anything that the client might care about, and bookmarking or caching the results of a search-engine query is just as useful as bookmarking or caching a static HTML page.
