Looping and count item into a multidimensional array with PHP

Question

I've this array:

Array
(
    [USA] => Array
        (
            [0] => Array
                (
                    [Name] => Apple
                    [Item] => Phones and Computers
                )
            [1] => Array
                (
                    [Name] => McDonalds
                    [Item] => Food
                )

        )
    [China] => Array
        (
            [0] => Array
                (
                    [Name] => Lenovo
                    [Item] => Computers
                )
        )
)

I would like to loop into it and echo the count of items for each country (USA and China).

So my try was this one:

foreach ($arr as $key => $value) {
    echo count($arr[$value]);
    echo '<br />';

    foreach ($value as $subkey => $subvalue) {
        echo $value." -> ".$subvalue['Name']." make ".$subvalue['Item']."<br />";    
    }
}

You don't need the echo count($newArr[$value]); just echo count($value);. And you can not echo $value in the second loop as it is array and not a string — dWinder

You can do this:

foreach ($arr as $country => $companies) {
    echo $country . " has " . count($companies) . " item <br />";

    foreach ($companies as $k => $company) {
        echo $company['Name'] . " make " . $company['Item']."<br />";    
    }
}

Keep your variable with meaningful name can make life much easier
