    TypeError

    (PHP 7, PHP 8)

    Einführung

    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.

    declare(strict_types=1); //if without this line the result is different

    $a = [1,2=>[3,4]];

    try{

        count($a, COUNT_RECURSIVE, 'toto and blabla');

    }catch(TypeError $e){

        echo $e->getMessage();

    }
