如何访问已被改造成一个对象数组的属性/值？

问题描述

我如何可以访问哪些已被改造成一个对象的属性/数组的价值呢？举例来说，我想在索引0来访问值，

  $ OBJ =（对象）阵列（'qualitypoint'，'技术'，'印度'）;
的var_dump（$ obj-大于0）;
 

错误

解决方案

The reason you can not access values via $obj->0 its because it against PHP variable naming see http://php.net/manual/en/language.variables.basics.php for more information. even if you use ArrayObject you would still have the same issues

but there is a patch to this ... you can convert all integer keys to string or write your own conversion function

Example

$array  = array('qualitypoint', 'technologies', 'India' , array("hello","world"));
$obj = (object) $array;
$obj2 = arrayObject($array);
function arrayObject($array)
{
    $object = new stdClass();
    foreach($array as $key => $value)
    {
        $key = (string) $key ;
        $object->$key = is_array($value) ? arrayObject($value) : $value ;
    }
    return $object ;
}
var_dump($obj2->{0}); // Sample Output
var_dump($obj,$obj2); // Full Output to see the difference


$sumObject = $obj2->{3} ; /// Get Sub Object
var_dump($sumObject->{1});  // Output world

Output

   string 'qualitypoint' (length=12)

Full output

object(stdClass)[1]
  string 'qualitypoint' (length=12)
  string 'technologies' (length=12)
  string 'India' (length=5)

    array
      0 => string 'hello' (length=5)
      1 => string 'world' (length=5)

object(stdClass)[2]
  public '0' => string 'qualitypoint' (length=12)
  public '1' => string 'technologies' (length=12)
  public '2' => string 'India' (length=5)
  public '3' =>
    object(stdClass)[3]
      public '0' => string 'hello' (length=5)
      public '1' => string 'world' (length=5)

Multi Array Outpur
