trying to undersnatd OO php code

[wolf73]

I am trying to understand the following code. In the function below. Buyer is a class and , and it has a method find_all that we are calling right?
and then $this->sites is a variable, correct, to which we are assingning the value returned by method find_all, correct? But if I print
$this->sites, it prints an array? something like this

"Array ( [0] => Buyer Object ( [table_name] => buyers [database_connection_name] => [all_fields] => Array ( ) [integrity_errors] => "





*@var array
*/
protected $sites;
protected $site;



public $buyer_carrier_weight = Array();



public function mobilebuyers()
{
$this->sites = Buyer::find_all("Buyer");
// $this->render("list_buyers");

}

Since variables in PHP don't have explcit types the act of assiging a value to a variable, turns the variable into the type the value had.

Example:

$myvariable=1;
$othervariable="Soime string";
$myvariable=$othervariable;

?%myvariable started out being an integer, but when I assigned the value of $othervariable to it, it becomes a string.

So if find_all returns an array. assigning that to the variable turns the variable $sites into an array.
