Count number of items into a multidimensional array with PHP

Question

Supposing I have this array:

Array
(
    [Europa] => Array
        (
            [country] => France
            [capital] => Paris
        ),
        (
            [country] => Spain
            [capital] => Madrid
        )
    [Asia] => Array
        (
            [country] => Russia
            [capital] => Moscow
        )
)

How can I count to number of item containing in Asia or Europa`?

Thanks.

Assuming

  $myArray= [
    'Europa' => [
            'country' => France
            'capital' => Paris
        ],
        [
            'country' => Spain
            'capital' => Madrid
        ],
    'Asia' => [
            'country' => Russia
            'capital' => Moscow
        ],
  ];

you could use count() based on index

$numEuropa = count($myArray['Europa']);
$numAsia = count($myArray['Asia']);

Use count in array_map as:

$cnts = array_map("count", $array);

Or with loop:

foreach($array as $key => $val)
    echo $key . " count is: " . count($value);

Live example: 3v4l
