Loop into a multidimensional array with PHP

Question

I've got this type of multidimensional array in PHP:

Array
(
    [1] => Array
        (
            [0] => Array
                (
                    [Name] => France
                    [Capital] => Paris
                )

            [1] => Array
                (
                    [Name] => Italy
                    [Capital] => Rome
                )

        )

    [2] => Array
        (
            [0] => Array
                (
                    [Name] => Canada
                    [Capital] => Ottawa
                )

        )

)

How can I loop into it ?

I try from my search on documentation:

foreach ($countries as $country)
{
  foreach ($country["Name"] as $name)
  {
     $capitals = array();
     foreach ($name["Capital"] as $capitals)
     {
       $capitals[] = $capital["Name"];
     }
     print implode(",", $capitals);
  }
}

Desired output should be:

Capital of `France` is `Paris`.
Capital of `Italy` is `Rome`.
Capital of `Canada` is `Ottawa`.

Could you please point me into the right direction ?

Thanks.

@mikeyjk you may retract your dupe link because for this question recursion is overkill. — mickmackusa

You must use two loops to access the lowest subarray, then you can access the values by their keys (Name and Capital).

Code: (Demo)

$array=[
    1=>[
        ['Name'=>'France','Capital'=>'Paris'],
        ['Name'=>'Italy','Capital'=>'Rome']
    ],
    2=>[
        ['Name'=>'Canada','Capital'=>'Ottawa']
    ]
];

foreach($array as $subarray){
    foreach($subarray as $subset){
        echo "Capital of `{$subset['Name']}` is `{$subset['Capital']}`.<br>";
    }
}

Output:

Capital of `France` is `Paris`.
Capital of `Italy` is `Rome`.
Capital of `Canada` is `Ottawa`.

just update the foreach loop

foreach ($countries as $country)
{
  foreach ($country as $cdata)
  {
     echo "Capital of '".$cdata['Name']."' is '".$cdata['Capital']."'<br/>".
  }
}

This is a late duplicate of my method, therefore it adds no value to the page.

That is understandable, but the fact remains that it is a late duplicate. You should delete it on principle, but I can see that you have received an undermining upvote so now you are less likely to do the right thing. Thanks Upvote Pixies.
