我有這個數組：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 ) ))我想介紹一下它，并回顯count每個國家（美國和中國）的商品。所以我的嘗試是這樣的：foreach ($arr as $key => $value) { echo count($arr[$value]); echo '<br />'; foreach ($value as $subkey => $subvalue) { echo $value." -> ".$subvalue['Name']." make ".$subvalue['Item']."<br />"; }}

你可以這樣做：
foreach ($arr as $country => $companies) {
echo $country . " has " . count($companies) . " item <br />";
foreach ($companies as $k => $company) {
echo $company['Name'] . " make " . $company['Item']."<br />";
}
}
