Question

I have a string manipulation class that I need in views and in controllers also!
I saw that cake reuses code in Components and in Helpers for this type of situations which on my opinion breaks the OOP logic (eg. Session->read)!

Instead of doing this I created a vendor class which I imported in a StringsHelper and in a StringsComponent. I then created an identical function which instanciates the Vendor/String class and returns the results from the corresponding function. This is not quite inheritance and still redundant, but if I change code in my class it changes everywhere.

Is there a better way to do this?

You do not need to wrap this kind of class in a Helper or a Component.

You could simply create a class with static methods and put it in APP/Lib like mentioned by Mark.

<?php
class StringTool{

  public static function manipulate($string){
   ...
  }

}

and then use it in whatever class you need, wether in a Component, a Helper, a Model, etc.

<?php
$s2 = StringTool::manipulate($s1);
