Question

How can I access the property/ value of an array which has been converted into an object? For instance, I want to access the value in the index 0,

$obj = (object) array('qualitypoint', 'technologies', 'India');
var_dump($obj->0);

error,

Parse error: syntax error, unexpected T_LNUMBER, expecting T_STRING or
T_VARIABLE or ‘{‘ or ‘$’ in C:…converting_to_object.php on line 11

Answer 1

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
