TypeError

(PHP 7, PHP 8)

Einf├╝hrung

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).
