loop multidimensional array

[ChenXiu]

my preg_match_all works perfectly. I just can't figure out how to loop through the "$matches" array it creates.
preg_match_all( $pattern , $string , $matches);

The code print_r($matches) yields the following super simple array.

(
    [0] => Array
        (
            [0] => 123456wordsandwordsandmorestuff$40.97
            [1] => 987654wordsandmorewords$26.79
        )

    [1] => Array
        (
            [0] => 123456  <----------this goes with the [0] below
            [1] => 987654  <----------this goes with the [1] below
        )

    [2] => Array
        (
            [0] => $40.97  <-----------this goes with the [0] above
            [1] => $26.79  <-----------this goes with the [1] above
        )

)

The problem is I can't figure out how to do the foreach() loop to get this:

SKU number 123456 costs $40.97
SKU number 978654 costs $26.79

I know the answer will be embarrasingly simple..... but I've tried at least 200 different foreach variations and I am close to giving up.

Thanks.

foreach(array_keys($matches[1]) as $key)
{
	echo "SKU number {$matches[1][$key]} costs {$matches[2][$key]}<br>";
}

@mac_gyver THANK YOU!
The $matches[1][$key] <--- This is the one thing that I didn't try. That "$key" variable in that spot.
Thank you again!
