If you want your view helper to contain additional methods besides its constructor, make sure you return the object instance and do something like this:

Class Zend_View_Helper_MainHelpers {
  public function mainhelpers() {
      return $this;
  }
  public function foo(){
    $output="ok 1";
    return $output;
  }

  public function bar(){
   $output="ok 2";
   return $output;
  } 
}

Now call your helper methods like this:

$this->mainhelpers()->foo()
$this->mainhelpers()->bar()

Judging from your code example, it seems you are trying to encapsulate more than one view helper inside one class. You are probably better of by creating more view helpers:

class Zend_View_Helper_Foo()
{
     public function foo() 
     {
         // do stuff
     }
}

class Zend_View_Helper_Bar()
{
     public function bar() 
     {
         // do more stuff
     }
}
