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.
