Match Construct in PHP

In PHP 8.0, a special construct match appeared, representing a simplified version of switch. This construct is also used to select one value from a series of values. Here is its syntax:

php<?php
  match (variable) {
    value1 => result1,
    value2 => result3,
    value3 => result3,
    default => default value
  }
?>

What comes after the => operator is returned as the result of the match operation and can be assigned to a variable. Let's try it in practice:

php<?php
  $lang = 'ru';
  
  $res = match ($lang) {
    'ru' => '111',
    'en' => '222',
    'de' => '333',
    default => 'unsupported language'
  };
  
  echo $res;
?>
