PHP：声明数组元素有值同样指定其他元素吗？

Question

Please see the example:

$array = array('001' => 'A', '002' => 'B', '002' => value of 001);

I want to declare an array like above. But I need the value of element 002 is always same of element 001. How can I do that?

Please help me. Thank you so much.

Since your question does not clarify where the values are coming from, i'd just say you may use

$val1 = 'A';
$array = array(
    '001' => $val1,
    '002' => $val1,
);
