PHP somo la 58: static method kwenye PHP

STATIC METHOD

Hii ni method ambayo inaweza kutumika moja kwa moja bila ya kutengeneza class instance (yaani bila ya kutengeneza object). Kutengeneza static method tutatumia keyword static . angalia mifano hapo chini kwanza nitakuletea mfano wa function ambayo sio static. Na kisha ambayo ni static.

<?php

class gari {

   public function tangazo() {

       echo "Tunauza gari";

   }

}

$my = new gari();

$my->tangazo();

?>

Utaona hapo ili tuweze kuitumia method tangazo imetubidi kwanza kutengeneza instance of class hapo tumeanza kwanza kutengeneza object $my = new gari(); Wacha sasa tuone mfano wa method hii hii ila ikiwa static utaona hapo hatuna haja ya kutengeneza object tena yaani instance of class. Pia tutatumia scope operator (::)

<?php

class gari {

   public static function tangazo() {

       echo "Tunauza Gari";

   }

}

gari::tangazo();

?>

<?php

class gari {

   public static function tangazo() {

       echo "Tunauza magari";

   }

   public function __c...
