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.

class TypeError extends Error {

/* Inherited properties */

protected string $message = "";

private string $string = "";

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)

}

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.
