Question

I need to make a key name from a array a reference to a different variable.

Like this:

$keys = array('name' => 'abc');

$arr[&$keys['name']] = array();

But it doesn’t work:(

is there any solution?

Answer 1

Leave the & away and ensure that $arr is set to an array before:

$arr = array();
$arr[$keys['name']] = array();
