PHP casting array to object [duplicate]

Question

Casing an Array with Numeric Keys as an Object

I made a casting from array to object and I'm confused:

$arr = range(1,3);
$obj = (object) $arr;
var_dump($obj)

object(stdClass)#2 (5) {
  [0]=>
    int(1)
  [1]=>
    int(2)
  [2]=>
    int(3)
}

The question is: How to access the object attributes in this case? $obj->0 causes syntax error.

Answer 1

You can't access these object properties unless you cast back to an array. Period. If you have to do this for some reason, set the array keys to something else.

Answer 2

In this case the only thing I can think is to access properties using a foreach like this:

foreach($obj as $key => $value)
   var_dump("$key => $value");

but of course this won't solve the base problem.
