title: How to define own functions in zend framework
body: <p>Actually I wanted to know that is there any way to define and call a function in Zend framework which does not need to put with $this like pr() function in cake php. I want to define a such a function which can be called directly in all controllers and views in zend framework. Can it be done by putting all functions in helper and use them without writing $this in front of them. </p>
  
  <p>For example I wanted to make a function arrprint() to print the array in helper and use it globally with only by writing simply arrprint();</p>
  
  <p>Please help me</p>
