Re: Re: OOP - Calling methods from classes that are inheriting?

} $class=new otherClass(); echo $class->otherFunc(); oh yes, it's that simple. 2 things to remember: 1. If you want to see output, actually make sure the function you call RETURNS any output in the first place. ($hello = "Yay!!"; isn't returning anything) 2. parent::* calls on the parent class in a static context. If your class extends another, it automatically inherits all functions from that class, unless it overwrites it itself. So you can simply use $this->func() in your child class.

not true (well you can use $this->func() in this case) ... but parent::* assumes the context your in (i.e. static or not): <?php class Test { static function func1() { echo __METHOD__,"\n"; } function func2() { echo __METHOD__," called from ", get_class($this), "\n"; } } class TestTwo extends Test { static function func1() { parent::func1(); } function func2() { parent::func2(); } } $t2 = new TestTwo; TestTwo::func1(); $t2->func2();

Hi, maybe if I post below what I'm trying to do it may make more sense: class myClass {

        public function func() {
            $hello = "Yay!!";
        }
    }

    class otherClass extends myClass {
        public function otherFunc() {
            echo parent::func();
        }
    }

    $class=new otherClass();
    echo $class->otherFunc();

Nothing outputs. Sorry I am slightly new to OOP so there may be a simple fix for this?

use a return statement, just like standalone functions, assuming you want to output the "Yah!!".

Hope I have made myself as clear as possible!

I did'nt understand what you mean, but I guess you're seeking for the parent keyword. Read again the PHP manual about OOP. -- Mickaël Wolff aka Lupus Michaelis http://lupusmic.org -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
