TypeError

    (PHP 7, PHP 8)

    Introduction

    A TypeError may be thrown when:

    • The value being set for a class property does not match the property's corresponding declared type.
    • The argument type being passed to a function does not match its corresponding declared parameter type.
    • A value being returned from a function does not match the declared function return type.

    protected int $code;
    protected string $file = "";
    protected int $line;
    private array $trace = [];
    private ?Throwable $previous = null;
    /* Inherited methods */
    public Error::__construct(string $message = "", int $code = 0, ?Throwable $previous = null)

    Changelog

    Version Description
    7.1.0 In strict mode, passing an incorrect number of arguments to a built-in PHP function no longer results in a generic TypeError. Instead, a more specific ArgumentCountError, which extends TypeError, is thrown.
