php - Calling a non-static method from a static method -

i think basic functionality, please help. how can call non-static method static-method in php.

class country {     public function getcountries() {         return 'countries';     }      public static function countriesdropdown() {         $this->getcountries();     } } 

preferred way..

it better make getcountries() method static instead.

<?php  class country {     public static function getcountries() {         return 'countries';     }      public static function countriesdropdown() {         return self::getcountries();     } } $c = new country(); echo $c::countriesdropdown(); //"prints" countries

adding self keyword displays php strict standards notice avoid that can create object instance of same class , call method associated it.
