Globals

[The-Last-Escape]

where do I find about superglobals in the manual at

[a href=\"http://www.php.net\" target=\"_blank\"]http://www.php.net[/a]

the following

Name

Functionality

 

$GLOBALS

Contains all global variables in your script, including other superglobals. This is not generally recommended for use, unless you are, for some reason, not sure where a variable will be stored. $GLOBALS has been available since PHP 3, and its operation has not changed.

 

$_GET

Contains all variables sent via a HTTP GET request. That is, sent by way of the URL. Users of older PHP versions will recognise this as being the same as $HTTP_GET_VARS array, which, although deprecated, is still available for use.

 

$_POST

Contains all variables sent via a HTTP POST request. This is similar to the old $HTTP_POST_VARS array, which, although deprecated, is still available for use.

 

$_FILES

Contains all variables sent via a HTTP POST file upload. This is similar to the old $HTTP_POST_FILES array, which, although deprecated, is still available for use.

 

$_COOKIE

Contains all variables sent via HTTP cookies. This is similar to the old $HTTP_COOKIE_VARS array, which, although deprecated, is still available for use.

 

$_REQUEST

Contains all variables sent via HTTP GET, HTTP POST, and HTTP cookies. This is basically the equivalent of combining $_GET, $_POST, and $_COOKIE, and is less dangerous than using $GLOBALS. However, as it does contain all variables from untrusted sources (that is, your visitors), you should still try to steer clear unless you have very good reason to use it. There's no equivalent to $_REQUEST in versions of PHP before v4.1.

 

$_SESSION

Contains all variables stored in a user's session. This is similar to the old $HTTP_SESSION_VARS array, which, although deprecated, is still available for use.

 

$_SERVER

Contains all variables set by the web server you are using, or other sources that directly relate to the execution of your script. This is similar to the old $HTTP_SERVER_VARS array, which, although deprecated, is still available for use.

 

$_ENV

Contains all environment variables set by your system or shell for the script. This is similar to the old $HTTP_ENV_VARS array, which, although deprecated, is still available for use.

 

 

Not sure where to find those at in the manual, thanks.
