Call function from another function

[eluser]luukskywalker[/eluser]
I have a small question.

I have 2 functions in 1 controller
Say Function A and Function B

Is it possible to call function B at the end of Function A?
If so, how is this done?

I know i can call a view but i don't want a view at the end of function A

If the second function is an action with its own view you could redirect to that action

Code:

redirect('controller/functionb');

Or if the function is just some controller logic you can call the method using:

Code:

$this->function_b();

great
This works fine
Thank you!

No problem,

Also if the method is just controller logic then put an underscore before the function name so that it can't be accessed from a URL e.g. http://website/controller/function_b

Code:

$this->_function_b();

This "http://website/controller/function_b" will no longer work.

is it also possible to send variables from function a to function b?

Because i want something like this(this is just an example):

Code:

Function_a(){
  
  $foo = "1";
  $this->_function_b($foo);
}

Function_b(){
if($foo){
      
echo $foo+1;

}else{

$foo = "10";
echo $foo;
}
