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

Starting with PHP 8 (Nov 2020), you can use match:

<?php

function test($string) {
   return match ($string) {
      'test1' => 'Test 1: ',
      'test2' => 'Test 2: '
   } . $string;
}

Although in this case you could just use an array:

<?php

function test($string) {
   return [
      'test1' => 'Test 1: ',
      'test2' => 'Test 2: '
   ][$string] . $string;
}

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.
