SplArray

SplArray其实是对ArrayObject的实现。

  1. $spl = new \Core\Component\Spl\SplArray(array(
  2.     "a"=>1,
  3.     "b"=>array(
  4.         "sub"=>'b1',
  5.         "sub2"=>"b2"
  6.     ),
  7.     "c"=>array(
  8.         "sub"=>'c1',
  9.         "sub2"=>"c2"
  10.     )
  11. ));

get

  1. var_dump($spl->get("a"));
  2. int(1)
  4. var_dump($spl->get("c.sub"));
  5. string(2) "c1"
  7. var_dump($spl->get("*.sub"));
  8. array(2) {
  9.     ["b"]=>
  10.     string(2) "b1"
  11.     ["c"]=>
  12.     string(2) "c1"
  13. }

set

  1. $spl->set("a",2);
  2. var_dump($spl->get("a"));
  3. $spl->set("c.sub",2);
  4. var_dump($spl->get("c.sub"));

getArrayCopy

  1. var_dump($spl->getArrayCopy());
  2. array(3) {
  3.   ["a"]=>
  4.   int(1)
  5.   ["b"]=>
  6.   array(2) {
  7.     ["sub"]=>
  8.     string(2) "b1"
  9.     ["sub2"]=>
  10.     string(2) "b2"
  11.   }
  12.   ["c"]=>
  13.   array(2) {
  14.     ["sub"]=>
  15.     string(2) "c1"
  16.     ["sub2"]=>
  17.     string(2) "c2"
  18.   }
  19. }

__toString

  1. echo $spl;
  2. {"a":1,"b":{"sub":"b1","sub2":"b2"},"c":{"sub":"c1","sub2":"c2"}}

注意：SplArray中对toString方法的实习实际上是json_encode()
