PHP 8 匹配表达式代码

echo match (8.0) {
    '8.0' => "Oh no!",
     8.0 => "This is what I expected",
};
//> This is what I expected

PHP 7 切换代码

switch (8.0) {
  case '8.0':
    $result = "Oh no!";
    break;
  case 8.0:
    $result = "This is what I expected";
    break;
}
echo $result;
//> Oh no!

1. 哪一个能提供更好的性能？
2. 匹配和切换的用例。
