class - PHP: what is the difference between $object::method and $object->method? -


i write:

$object->method

but see:

$object::method

what's difference?

-> used when referring member of object.

:: scope resolution operator , used refer static member of class. example 

class test {     public static function vehicle() {         echo "bus";     }      public function automobile() {         echo "car";     } }

you call function automobile() as

$test = new test(); $test->automobile();

and call vehicle function 

test::vehicle();
