Question

I was wondering if anyone could help me restructure a predefined php array. The output of my current array is:

Array
(
    [71-ctns] => 1
    [71-units] => 1
    [308-units] => 1
    [305-ctns] => 1
    [306-units] => 2
)

And I would like it to look like:

Array
(
    [71] => Array
        (
            [ctns] => 1
            [units] => 1
        )
    [308] => Array
        (
            [units] => 1
        )

    [305] => Array
        (
            [ctns] => 1
        )
    [306] => Array
        (
            [units] => 2
        )
)

Is this possible?

Answer 1

This should do it

$merged = array();
foreach($a as $k=>$v){
    $t = explode('-',$k);
    $id = intval($t[0]);
    if(!array_key_exists($id, $merged))
        $merged[$id] = array();
    $merged[$id][$t[1]] = $v;
}

EDIT:

Sorry you should use explode instead of split.
