Question

如何匹配键和值（缩写和国家/地区）并计算总百分比？

$def = array( "AF" => "Afghanistan", "AL" => "Albania", "DZ" => "Algeria", "AD" => "Andorra", ...)
$var      = ["AF", "AF", "DZ"];

结果： 66％阿富汗 33％阿尔及利亚

Answer 1

我们可以使用array_diff_key（）比较两个数组的键和值，

<!DOCTYPE html>
<html>
    <body>

        <?php
        $a1=array("a"=>"red","b"=>"green","c"=>"blue");
        $a2=array("a"=>"red","c"=>"blue","d"=>"pink");

        $result=array_diff_key($a1,$a2);
        print_r($result);
        ?>

    </body>
</html>

希望，这会有所帮助。

Answer 2

使用array_count_values：

      volumeMounts:
        - mountPath: $JFROG_PATH
          name: secrets
        - mountPath: /config
          name: vault
