Example

PHP Superglobals

OLD GET METHOD (Short)	NEW GET METHOD
$_GET['key']	sg::get('g.key')
$_POST['key']	sg::get('p.key')
$_COOKIE['key']	sg::get('c.key')
$_SERVER['key']	sg::get('s.key')
$_FILES['key']	sg::get('f.key')

OLD GET METHOD (Long)	NEW GET METHOD
$_GET['key']['key1']['key2']	sg::get('g.key.key1.key2')
$_POST['key']['key1']['key2']	sg::get('p.key.key1.key2')
$_COOKIE['key']['key1']['key2']	sg::get('c.key.key1.key2')
$_SERVER['key']['key1']['key2']	sg::get('s.key.key1.key2')
$_FILES['key']['key1']['key2']	sg::get('f.key.key1.key2')

User-defined global variables

sg::set

<?php
var_dump(sg::set('test', 'test apple'));
var_dump(sg::set('user.0.0', 'user 0 apple'));
var_dump(sg::set('user.0.1', 'user 1 apple'));
var_dump(sg::set('user.a.a', 'user a apple'));
var_dump(sg::set('user.a.b', 'user b apple'));複製代碼

The above example will output:

bool(true)
bool(true)
bool(true)
bool(true)
bool(true)

sg::get

<?php
var_dump(sg::get('test', 'test apple'));
var_dump(sg::get('user');
var_dump(sg::get('not_found', 'def');
var_dump(sg::get('user.1.2.3.4'));複製代碼

The above example will output:

string(10) "test apple"
array(2) {
  [0]=>
  array(2) {
    [0]=>
    string(12) "user 0 apple"
    [1]=>
    string(12) "user 1 apple"
  }
  ["a"]=>
  array(2) {
    ["a"]=>
    string(12) "user a apple"
    ["b"]=>
    string(12) "user b apple"
  }
}
string(3) "def"
NULL

sg::has

<?php
var_dump(sg::has('test'));
var_dump(sg::has('not_found'));複製代碼

The above example will output:

bool(true)
bool(false)

sg::del

<?php
var_dump(sg::del('test'));
var_dump(sg::del('user.0.1'));
var_dump(sg::get('user');複製代碼

The above example will output:

bool(true)
bool(true)

    string(12) "user 0 apple"
  }
  ["a"]=>
  array(2) {
    ["a"]=>
    string(12) "user a apple"
    ["b"]=>
    string(12) "user b apple"
  }
