TypeError

(PHP 7, PHP 8)

Einführung

There are three scenarios where a TypeError may be thrown:

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.
An invalid number of arguments are passed to a built-in PHP function (strict mode only).
