[SOLVED] Private functions

[mikesta707]

I never quite grasped the concept of private functions vs. public functions. What exactly is the difference. Are private functions only callable inside the class itself?

 

say i had a class

class foo{
public function hi(){
$this->bar();
}
private function bar(){
echo "can't touch this";
}
}

$foo = new foo();

//would this not work
$foo->bar();

//but this wwould work?
$foo->hi();

 

 

Is there more than just that?

That's pretty much it.  Private methods have their uses, typically as bookkeeping/initialization methods that shouldn't be used by the client system.
