Seltsames Verhalten von count()?

[Jörg]

Hallo Forum,

ich habe folgenden Quellcode:

echo("<pre>");
print_r($myArray);

if(count($myArray > 0)) {
echo "Hello World";
exit;
//... usw.
}

Der ergibt in der Ausgabe:

Array

    [0] => Array
        (
            [0] => Array
                (

Fatal error:  Uncaught TypeError: count(): Argument #1 ($value) must be of type Countable|array, bool given in

Ist mein assoziatives Array für count() seit php 8 nicht mehr Array genug?
