如何计算php关联数组中的项目数
问题描述：
我有一个如下数组.
Array
(
[0] => Array
(
[item] => Banana Cream Cheesecake
[item_id] => 3
[product] => Desserts
)
[1] => Array
(
[item] => Banana Cream Cheesecake
[item_id] => 3
[product] => Desserts
)
[2] => Array
(
[item] => Banana Cream Cheesecake
[item_id] => 3
[product] => Desserts
)
[3] => Array
(
[item] => Banana Cream Cheesecake
[item_id] => 3
[product] => Desserts
)
[4] => Array
(
[item] => Milk
[item_id] => 2
[product] => Soda
)
[5] => Array
(
[item] => Banana Cream Cheesecake
[item_id] => 3
[product] => Desserts
)
)
我要打印:-
Banana Cream Cheesecake = 5
该怎么做?
答
$count = 0;
foreach ($array as $key=>$value) {
if ($value ['item'] == 'Banana Cream Cheesecake') {
$count++;
}
}
echo $count;
