TypeError

    (PHP 7, PHP 8)

    简介

    会抛出TypeError 的情况:

    • 为类属性设置的值与该属性申明的类型不匹配。
    • 传递给函数的参数类型与函数预期声明的参数类型不匹配。
    • 函数返回的值与声明的函数返回类型不匹配

    类摘要

    class TypeError extends Error {
    /* 继承的属性 */
    protected string $message = "";
    private string $string = "";
    protected int $code;
    protected string $file = "";
    protected int $line;
    private array $trace = [];
    private ?Throwable $previous = null;
    /* 继承的方法 */
    public Error::__construct(string $message = "", int $code = 0, ?Throwable $previous = null)
    final public Error::getMessage(): string
    final public Error::getPrevious(): ?Throwable
    final public Error::getCode(): int
    final public Error::getFile(): string
    final public Error::getLine(): int
    final public Error::getTrace(): array
    final public Error::getTraceAsString(): string
    public Error::__toString(): string
    private Error::__clone(): void
    }

    更新日志

    版本 说明
    7.1.0 当在严格模式下向内置 PHP 函数传递无效数量的参数时，不再抛出 TypeError。 相反，会抛出 ArgumentCountError
