[RESOLVED] str into array

[zzz]

this must be a really simple thing, but I'm probably going in a wrong direction.

I have a sting:

$str = 33,34,55,67;

I need to turn it into an array

[22] => [33], [34] => [34], [55] => [55], [67] => [67]

I tried expload but got the wrong results

$arrayNew = implode(",", $str);
// result
[0] => [33], [1] => [34], [2] => [55], [3] => [67]

Why not just do:

$array = explode(',', $string);
$arrayNew=array();
foreach($array as $val)
    $arrayNew[$val] = $val;

It's a couple extra lines, but it does what you want.

Even simpler yet:

$str = '33,34,55,67'; 
$array = explode(',', $str);
$array = array_combine($array, $array);

EDIT:
But of course, we are assuming that you want an array where the keys are the same as the corresponding values. If so, you have a typo where the first key is 22 and the first value is 33.

Brilliant.
