PHP Array handling for first children

Question

I'm so tired of arrays today - thrown me all over the place.

So, here's the output of an array:

Array
(
[2010091907] => Array
    (
        [home] => Array
            (
                [score] => Array
                    (
                        [1] => 7
                        [2] => 17
                        [3] => 10
                        [4] => 7
                        [5] => 0
                        [T] => 41
                    )

                [abbr] => ATL
                [to] => 2
            )

Array
(
[2010091909] => Array
    (
        [home] => Array
            (
                [score] => Array
                    (
                        [1] => 7
                        [2] => 17
                        [3] => 10
                        [4] => 7
                        [5] => 0
                        [T] => 41
                    )

                [abbr] => ATL
                [to] => 2
            )

Array
(
[2010091901] => Array
    (
        [home] => Array
            (
                [score] => Array
                    (
                        [1] => 7
                        [2] => 17
                        [3] => 10
                        [4] => 7
                        [5] => 0
                        [T] => 41
                    )

                [abbr] => ATL
                [to] => 2
            )

I'm going to be writting a preg_match to iterate each [2010091907], but before I can, I do not understand how to get this piece of information, or how to call it. I'd be doing something like:

$json=json_decode($data,true);
foreach ($json['dont-know-what-to-call-it'] as $key => $value) {
            echo "Key: ".$key."; Value: ".$value."<br />";
}

I just don't know how to call each one of those [2010091901] blocks, like what name I'm suppose to call them as. I know how to call the stuff under score, since it's named "score", and the data is under all that. I don't know how to get the key/value of the initial "sections" of the array. In the end, I'm going to want to grab each [2010091901], manipulate/use the data that is inbetween each one of the [2010091901], and then go to the next "record".

Answer 1

$date_keys = array_keys($json) would give (0 => 2010091907, 1 => 2010091909, ...) . then you could do

foreach ($date_keys as $d) {
   foreach ($json[$d] as $key => $value) {
...

Also, if you do not actually need the indices of the outer array (the date values - 2010091907, etc) than you could just do

foreach ($json as $j) {
   foreach ($j as $key => $value) {
...

ignoring the keys of $json

Answer 2

Can't you just nest foreach()s?

foreach($jsondata as $somedate => $value){
    //do you actually need $somedate?
    foreach($value['home']['score'] as $score){
        echo $score.PHP_EOL;
    }
}

Answer 3

You can just do

$json = json_decode($data, true);
foreach($json as $ymd => $data)
{
    // $ymd = [2010091907, 2010091909,… ]
    // $data is the array starting with the key home. so $data['home']['score'][1] = 7 for the first iteration
}

This answer your question? It's not 100% clear what you're asking
