SG Full name Superglobals, References all variables available in global scope, SG has extended a new way to manage PHP superglobals variables, Make the management of PHP superglobals variables simple and unified.
These superglobal variables managed by SG are: $_SERVER, $_GET, $_POST, $_FILES, $_COOKIE, $_SESSION, $_REQUEST, $_ENV.
The version v3.0.1 support read raw data from the request body. In the case of POST requests.
Very important point: it is very simple.
- Simple, Fast, Lightweight
- Access PHP superglobals zero-copy, Synchronously update PHP Superglobals variables
- Support custom call function name, Default call PHP trim
- Solve the problem of undefined series when using PHP Superglobals variables (Undefined variable, Undefined offset)
- Use static function method, Replace the PHP array dimension with a decimal point
- Use global statement, Replace the PHP array dimension with a underline
- Support for global $variable the option configuration, Default level one lookup
- Support for read raw data from the POST requests
- PHP 5.4 +
- PHP 7.0 +

- When management PHP sessions (MapKey = n), First call the function session_start()
| PHP Predefined Superglobals | SG Key | global statement | Method Example |
|---|---|---|---|
| $GLOBALS | - | - | sg::all() |
| $_SERVER | s | global $s | sg::get/set/has/del('s') |
| $_GET | g | global $g | sg::get/set/has/del('g') |

| $_FILES | f | global $f | sg::get/set/has/del('f') |
| $_COOKIE | c | global $c | sg::get/set/has/del('c') |
| $_SESSION | n | global $n | sg::get/set/has/del('n') |
| $_REQUEST | r | global $r | sg::get/set/has/del('r') |
