Yes it does have nulls. https://3v4l.org/vgfI1
See http://php.net/support.php if you're still having
trouble understanding this.

But at at the point where I am trying to access an element of $test array, the argument $param of
getPost function is well-formated, string without any nulls. Why still I cant use that argument as
array key ? It contains no 0, no nulls.

The array keys are not simply class+property. They contain null characters. It's how PHP
manages private class properties, and casting to an object will expose those nulls to you.

Create a method inside the class that returns the result of get_object_vars().

Description:
------------
Cannot access array key with hyphen in it if passing a variable as key, but it works with string.
Test script:
---------------
<?php
$test = array('customer-test1' => 1, 'customer-test2' => 2);
function getPost($param) {
global $test;
echo $param." = ".$test[$param]."<br/>";
return isset($test[$param]) ? $test[$param] : NULL;
}
class Customer {
private $test1;
private $test2;
function __construct() { }
}
$object = new Customer();
$arr = (array)$object;
$newArr = array();
foreach($arr as $key => $val) {
$newKey = str_replace(get_class($object), "", $key);
$newArr[$newKey] = getPost(strtolower(get_class($object))."-".$newKey);
}
