Why is array() always printed?

Question

JavaScript

function MessageShow()
{
    $Message = "";
    if (isset($_SESSION['message'])) $Message = $_SESSION['message'];
    print_r($Message);
    $_SESSION['message'] = array();
}

Answer 1

const getProp = (obj, path) => path.split('.').reduce((p, c) => p ? p[c] : null, obj);

const id = getProp(e, 'path.1.attributes.uid.textContent');

Or is there such a thing .

Answer 2

if (isset($_SESSION['message']) and $_SESSION['message']!=null) {
        $Message = $_SESSION['message'];
        print_r($Message);
    }
    $_SESSION['message'] = array();

Answer 3

Because it contains an empty array. $_SESSION['message']
