Help !! Create multiple array via string split

[Widow Maker]

Hello, here is a problem I've been trying to work out for the last hour or so. I have a string which I want to create a multiple array from, though in some cases, there may only be a depth of one.

Ie I want this

String1.String2 

Turned into

Array {
[String1][String2] } 

So I can put a value into this array, such as

echo( $ar['String1']['String2'] ); // results in 

Hello World

The value would proberly be a function parameter, so that isn't the problem. I've tried using this, which works, but not so if array is only one deep.

list( $first, $second ) = explode( '.', $key );
#
$array[$first][$second] = $parameterValue; 

Does anyone have any ideas ? Looked at using

foreach ( $x as $a ) { ... array_shift( ... ) ... } 

But no luck there either

Thanks in advance.

I have no idea how you turn String1.String2 into Hello World, care to explain again what you're trying to archive with a slightly better example?

Something more complicated that 'Hello World' I'm afraid

Okay. You have a string - created elsewhere, not important - which I've needed to split by the period in the string yes ? ie

module.administrator 

But also string could be without a period, ie

ViewNews 

I could easilly pass the above via an array - which I'm doing at the moment - but I'm making some improvements, so instead of passing an array, I'm ''Pushing'' all the

 $var => $value 

to the Controller directly. But since there are either one or two (or even more) depths to the target array, I decided to split/explode a string via the period, if you follow ?

Now, I have for example, this

...
<module>administrator</module>
... 

Which I then turn into this

 module.administrator 

Which on the Controller's ''Push'' method, would create this

 $array['module']['administrator'] = 'Some String'; 

Another point is I noticed that with my current methods, duplicate entries, ie

 ['module']['administrator'] 

could be over-written with, for example

 ['module']['editor'] 

Which is another problem

Hope this helps a lot more Gaheris ?

    function getKey(&$arr, $key, $seperator = '.')
    {
        foreach(explode($seperator, $key) as $subkey)
        {
            if (!is_array($arr) || !isset($arr[$subkey]))
                return NULL;
            $arr = $arr[$subkey];
        }
        return is_array($arr) ? NULL : $arr;
    }


    function setKey(&$arr, $key, $value, $seperator = '.')
    {
        foreach(explode($seperator, $key) as $subkey)
        {
            if (!isset($arr[$subkey]) || !is_array($arr[$subkey]))
                $arr[$subkey] = array();
            $arr = &$arr[$subkey];
        }
        $arr = $value;
    }


    $arr = array();

    setKey($arr, 'String1.String2', 'test');
    setKey($arr, 'module.administrator', 'module-administrator');
    setKey($arr, 'module.editor', 'module-editor');

    var_dump($arr);
    var_dump(getKey($arr, 'module.editor'));
