PHP 在 switch case 中翻译 ENUM 不起作用

Question

        echo $state;  //debug
        switch($state){
            case "Sleeping":
                $label = "Is Sleeping";
            case "Running":
                $label = "Is Running";
            default: 
                $label = "Could not retrieve state";
        }

$state从SQL数据库（Enum类型）填充，回显消息打印“Sleeping”，但$label填充默认值

在您的情况下，选择match（PHP 8）表达式明显更短，并且不需要语句break。

$state = "Running";
$label = match ($state) {
    "Sleeping"=> "Is Sleeping",
    "Running" => "Is Running",
    default => "Could not retrieve state"
};
echo $label; // "Is Running"
