我有这样的数组

Array ( [operator_15] => 3 [fiter_15] => 4 [operator_17] => 5 [fiter_17] => 5 [operator_19] => 4 [fiter_19] => 2 )

我想将这个数组分成2个数组:

1. 关键从 fiter_
2. 关键从 operator_

我使用了数组过滤器,它不起作用.还有其他选择吗？

$array = array_filter($fitered_values, function($key) {
            return strpos($key, 'fiter_') === 0;
        });

我有一个这种类型的数组,我想将一些元素转换为逗号separeted
