Loop into a multidimensional array with PHP and echo datas

Question

I'm pretty new in PHP and array.

I've this array:

Array
(
    [Africa] => Array
        (
            [City] => Algeria
        )

    [Asia] => Array
        (
            [Country] => China
        )

    [Europa] => Array
        (
            [City] => London
        )
)

How can I get something like:

- Africa : City is Algeria
- Asia : Country is China
- Europa : City is London

This is what I've tried:

foreach ($arr as $item => $val) {
    echo $item.' : '.$item[0].' is '.$val;
}

Thanks a lot for your help.

A nested `foreach` may be easier as you don't always have `city` as the key. — Nigel Ren, May 24 '21 at 13:07
`$item` is the *key* of your array (the continent string) so it makes no sense to access an offset on it. — El_Vanja, May 24 '21 at 13:09

That's a pretty basic example, so if you will only have one item under the continent:

foreach ($arr as $item => $val) {
    echo "$item : " . ($key = key($val)) . " is {$val[$key]}";
}

Or use current() or reset():

echo "$item : " .  key($val) ." is " . reset($val);

`array_key_first` may be better if you are going to get only the first key of the array. – Iván Pérez May 24 '21 at 13:24
Doesn't matter if there is only one. `array_shift()` will do it too. – AbraCadaver May 24 '21 at 13:31
