PHP square brackets in object variable - how to call the variable

Question

I have a simple answer I just can't solution to:

var_dump(obj) =

object(stdClass)#15 (3) {
  ["properties"]=>
  object(stdClass)#14 (2) {
    ["user_name"]=>
    string(4) "somename"
    ["email_address"]=>
    string(12) "[email protected]"
  ["arrays"]=>
  object(stdClass)#17 (1) {
    ["sites[]"]=>
    object(stdClass)#18 (4) {
      ["0"]=>
      int(1)
      ["1"]=>
      int(1)
      ["2"]=>
      int(0)
      ["3"]=>
      int(0)
    }
  }
}

How to call the 'sites[]' object in my 'obj'?

I tried the following:

obj->sites[]
obj->{'sites[]'}

Both options aren't working...

@Machavity, the variable being dumped is not an array, it's an stdClass object. — Ian

It might be better to clean up the code that generates that object, but you should be able to access the sites[] object via:

$sites = $obj->arrays->{'sites[]'};

However $sites will still be an object, so you would need to access its elements in a similarly awkward way:

echo $sites->{'0'};

~~It would be better to cast it to an array at that point:~~

$sites = (array) $obj->arrays->{'sites[]'};

~~Then you can access as an array:~~

echo $sites[0];

EDIT, seams you cannot access array elements indexed by a numerical string.

A better option (as discovered by a SO question i just posted about this) would be to use get_object_vars:

$sites = get_object_vars($obj->arrays->{'sites[]'});

Then you can access as an array:

echo $sites[0];

Lol, I forgot to add 'arrays' there, dumb me. I already cleaned up the naming. Thank you for your help
