Number of objects in PHP

Question

I work with PHP arraysand objects. I have been working with them for a long time. However, I am stuck in a problem that may have a very simple solution.

I have a variable $productsinside a function that gets a value when called. I am trying to count the objects in a variable to see how many products are inside it. I tried a simple function count($products)and count((array)$products)and it does not work. I know this is not the best way to count objects.

Is there any way to count them?

object(stdClass)#46 (3) {
  ["0"]=>
  object(stdClass)#47 (1) {
    ["productid"]=>
    string(2) "15"
  }
  ["1"]=>
  object(stdClass)#48 (1) {
    ["productid"]=>
    string(2) "16"
  }
  ["2"]=>
  object(stdClass)#48 (1) {
    ["productid"]=>
    string(2) "26"
  }
}

I need this to return 3

object(stdClass)#20 (1) {
  ["productid"]=>
  string(2) "21"
}

I need it back 1

              string(2) "15"
    }
