PHP8新特性之match

match类似switch

下面是switch

$bool = false;
switch ($bool) {
    case false: $result = 10;
    break;
    case true: $result = 20;
    break;
    default: $result = 30;
}
var_dump($result);

输出10

下面是match

$bool = false;
$result = match($bool) {
    false => 30,
    true => 40,
};
var_dump($result);

输出30
