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

Break is just a cautionary statement used to limit the control of switch stucture from going into another case...for example if you have three case statements and value is for first case and you have used case without any break structure then all the following cases will be executed inspite of the condition being satisfied only for the first case... Return can perform the asme function so it won't be a problem if you use return in place of break because return will take control away from the switch case statement which is the need at that moment...... hope it helps....
