PHP calling function within a class.

[jigney]

Here is the code what i do, To call a function within a class,
Which works fine, But i want to know that is there any other way to Call function within a class?
class demo {
public function demo_one(){
$this->demo_big();
$this->demo_small();
}

private function demo_big(){
// Code for demo_big
}

private function demo_small(){
// Code for demo_small
}

public function demo_test(){
// Code for demo_test
}
}

$demoObject = new demo();

$demoObject->demo_one();

$demoObject->demo_test();

You are trying to call a private function (method) from outside the parent class itself and that will throw a FATAL ERROR. If you truly need the ability to call that function from the "outside" then you can merely change it to a public function. More reading here:

hmmh ... it works or. so you want just know if there are other ways to achieve the same?

1. static methods

public function demo_one(){
// $this->demo_big();
// $this->demo_small();

self::demo_small();
self::demo_big();
}

private static function demo_big(){
echo 'demo_big';
}

private static function demo_small(){
echo 'demo_small';
}


2. call_user_func

public function demo_one(){
// $this->demo_big();
// $this->demo_small();

$methodsToCall = array('demo_big', 'demo_small');
foreach($methodsToCall as $methodName) {
if (method_exists($this, $methodName)) {
call_user_func(array($this, $methodName));
}
}
}
