find numeric key of associative index of array in array

Question

I can't understand how to get numeric index of "Index1" in such a structure:

$arr = array('Index','Index1' => array("one","two","three"),'Index2');

i'm trying to use array_search like so:

$index = array_search("Index1",$arr);

but it doesn't work; Thanks

`Index1` doesn't have a numeric index ([see for yourself](http://codepad.org/4vyRQYbd)) — kero, Sep 18 '14 at 13:40
The index is `Index1`. There's no "numeric index" for a string index. — deceze, Sep 18 '14 at 13:41
You could also write the array as `array(0 => 'Index', 'Index1' => .., 1 => 'Index2')` and produce the exact same structure — kero, Sep 18 '14 at 13:42

As mentioned, there is no numeric index for that element, as its key is a string.

However if you just want to find its position in the array:

$position = array_search("Index1",array_keys($arr),true);
