Do you need break in switch when return is used?

Question

I was wondering if I need to use \"break\" in \"switch\" function when \"return\" is used.

function test($string)
{
  switch($string)
  {
    case \'test1\':
            


        

Answer 1

No its not necessary , because when the key word return is called it will indicate that the particular function which the switch/case was called has come to an end.
