计算数组中的值

Question

好吧，这个小问题让我疯了。

这是$ strap_materials的print_r输出：

Array(
    [0] => steel
    [1] => leather
    [2] => polyester
    [3] => leather
    [4] => steel 
)

我想计算每个值存在多少次，并将每个和数放在一个数组中，如下所示：

Array(
    [0] => Array(
        "name"  => steel
        "count" => 2
    )
    [1] => Array(
        "name"  => leather
        "count" => 2
    )
    [0] => Array(
        "name"  => polyester
        "count" => 1
    )
)

我的目的是使用新创建的数组：

foreach($straps as $strap) {
    echo "Name: " . $strap->name;
    echo "Count: " . $strap->count;
}

我怎样才能做到这一点？

您可以使用array_count_values()：

$counts = array_count_values($strap_materials);

foreach ($counts as $name => $count) {
    ...
}
