按特定键计算值

Question

问题

我有一个棘手的问题，即只有当密钥amount等于name_pay时，如何计算密钥Click的值。我编写的PHP脚本只计算数组中的数量。 我试图将array_key_exists更改为array_count_values()但这是一个错误。

阵列

PHP

$click = 0;
    foreach($data["reports"][1] as $v) {
        if(array_key_exists('amount', $v)) $click++;
    }

Answer 1

这是你想要的吗？

$click = 0;
foreach($data["reports"][1] as $v) {
    $click += (isset($v['name_pay']) && $v['name_pay'] == 'CLICK')? $v['amount']:0;
}

我不确定你的代码中是什么$data["reports"][1]但是因为那是你在迭代的东西，我也在使用它。
