當(dāng)參數(shù)類型正確但是值不正確的時(shí)候會(huì)拋出 ValueError。 例如,當(dāng)函數(shù)期望是正整數(shù)時(shí)傳遞負(fù)整數(shù), 或者當(dāng)函數(shù)期望它不為空時(shí)傳遞空字符串/數(shù)組。
class ValueError extends Error {
/* 繼承的屬性 */
protected string $message = "";
private string $string = "";
protected int $code;
protected string $file = "";
protected int $line;
private array $trace = [];
private ?Throwable $previous = null;
/* 繼承的方法 */
