PHP：以编程方式将迭代器值附加到循环中的数组键名称是否可行？

Question

I have a multidimensional array object, and in a loop I would like to append an iterator to the key and obtain the value. Sample code for demonstration:

    $array_object->example1 = 1;
    $array_object->example2 = 2;


$i = 1;

while ($i <= 2) {

       echo ($array_object->example . $i); //this does not work
       //how to accomplish same?
       $i++
    }

Thank you in advance for any suggestions.

I think variable variables will solve your problem, immediately:

$example = "example" . $i;
echo $array_object->$example;

But you may want to consider making $array_object->example an array, and accessing it like:

echo $array_object->example[$i];
