一个获得结果的选项是使用resul将另一个值传递给array_map的 array_count_values 。

One option to get your result is to pass another value to array_map with the result of array_count_values.

然后，您可以在映射内确定基于索引的数字计数，例如 $ countValues [$ x] 和映射器一样。

Then inside the mapping you can determine to show the count for the number based on the index like $countValues[$x] just as for the mapper.

例如

foreach($out as $result) {
    $countValues = array_count_values($result);
    echo "<b>Possible Answer " . $m++ . " : </b><br> " . implode(' , ',
            array_map(function ($x) use ($mapper, $countValues) {
                $strCount = $countValues[$x] > 1 ? " (" . $countValues[$x] . ")" : "";
                return $mapper[$x] . $strCount . " - " . $x;
            }, array_unique($result))) . "
      <br><br>";
}

这将为您提供类似
