SuperGlobals is a PHP library for safe and convenient handling of SuperGlobals such as $_GET, $_POST, $_SESSION, $_COOKIE.

Safe because you can use special methods to validate or filter requested value "on the fly"
Convenient because it makes application code short and meaningful, without useless repetitions, making it ''extra'' DRY

Using this library you can:

write Get::get('key'); instead of isset($_GET['key']) ? $_GET['key'] : '';
put a default value as a second attribute like this: Get::get('foo', 'bar'); this returns 'bar' when $_GET['foo'] is not set.
use methods like Get::int('p'); for getting an integer value, for page number. If you want to use default "1" in this keys, you should write Get::int('p', 1);
use the same interface for different SuperGlobals: $_GET, $_POST, $_SESSION, $_COOKIE (use Get::get('foo'); for $_GET['foo'], or Cookie::get('foo'); for $_COOKIE['foo'])

We have such a methods:

get(string $key, string $default = '') : string - Returns the value of the preset key, or the preset default value.
int(string $key, int $default = 0) : int - Returns the value of the preset key, if it is integer or the preset default value.
float(string $key, float $default = 0) : float - Returns the value of the preset key, if it is float or the preset default value.
array(string $key, array $default = array()) : array - Returns the value of the preset key, if it is an array or the preset default value.
ident(string $key, string $default = '') : string - Returns the value of the preset key, if it contains only this: a-zA-Z0-9_- symbols, or the preset default value.
isDefined(string $key) : bool - Returns TRUE if the the the preset key is defined, or FALSE if it is not.
isNull(string $key) : bool - Returns TRUE if the value of the the preset key is not set, or FALSE otherwise.
isNotSet(string $key) : bool - Returns FALSE if the value of the the preset key is not set, or TRUE otherwise.
is1(string $key) : bool - Returns TRUE only if value of the $key == 1;
isEmpty(string $key, bool $ifNotSet = false) : bool - Returns TRUE if value of the $key == ''
