If you check out the documentation on arrays, you will see the second
code example shows the expected behavior of arrays in this case.
$arr = array("foo" => "bar", 12 => true);
echo $arr["foo"]; // bar
echo $arr[12]; // 1
Now, since each element can be indexed by either a string or an integer,
then you can do something like this:
$arr = array("1.2" => array(1,2,3,4));
$arr[0] = & $arr["1.2"];
That would set up your doubly indexed array so that you could use either
associative keys or numeric keys.
http://www.php.net/manual/en/language.references.php
PHP.net can explain how references work better than I can. Basically it
creates a "symbolic link" (to use a *nix term) to the key "1.2". It
shouldn't take up too much memory to do that.

Try
$try = $var["1.2"];
If your array looks like the one below then there is no $var[0] and
therefore you get NULL
