It's Scope Resolution Operator (also called Paamayim Nekudotayim). It allows you to access constants or static methods.

It allows you to call a static function/method in a class, without making an instance of the class:

class myClass{

static function myFunction(){
echo"foo";
}
}

now call it like this with ::

myClass::myFunction;

with a public function, you would have to make an instance:

$mycalssinstance= new myCalss;
//then call it
$mycalssfunction=$mycalssinstance->myFunction();

Call to a static (class) method. You can call this without an instance of the class.
