how to use common function in helper and component In Cakephp

Question

We are familiar with Components and Helpers in CakePHP.

I have an ABC Component and XYZ helper and both have same function (around 2000 lines total 4000 lines). there is any way to use same function in Controller and .CTP files. it's not good to use same function 2 time.

any method so i can use Component/Helper function in Helper/Component without rewrite ?

same method into component and helper >>

Component

class DATAComponent extends Component {

public $components = array('Session', 'THmail');

public function UsaStateList()
{ /********/}

Helper

class LabHelper extends AppHelper {
    public function UsaStateList()
    { /********/}
}

Well, you will have to rewrite something, it's not going to solve itself.

CakePHP is still PHP, so you can easily apply common patterns to keeps things DRY. The most straight forward way would probably be to move the shared functionality into an utility class that your component and helper can both use internally while leaving their public API unchanged.

Some of CakePHPs helpers do something similar, check for example the time helper.

• http://book.cakephp.org/2.0/en/core-utility-libraries/time.html#CakeTime

Traits might be an option too, depending on the amount of functionality being shared and how much it is tied to the use in a component/helper.
