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!!".

I did'nt understand what you mean, but I guess you're seeking for the
parent keyword. Read again the PHP manual about OOP.
