如何在阵列中找到重复和最高价值
原标题:How to find the duplicate and highest value in an array

我有这样的阵列。

array={ a => 2 , b => 5 ,  c => 6 ,  d => 6 ,  e => 2 };

阵列价值可能因“持久性有机污染物”变量而有所不同。 我的问题是,如何在我的阵列中找到最高价值,并恢复指数的关键。 就我而言,我需要获得奇和 d以及6份价值。 不知道如何做到这一点。 希望得到任何帮助。 感谢。

最佳回答
$max  = max(array_values($array));
$keys = array_keys($array, $max);
问题回答
$array = array(
   key1  => 22,
   key2  => 17,
   key3  => 19,
   key4  => 21,
   key5  => 24,
   key6  => 8,
);

function getHighest($array)
{
   $highest = 0;
   foreach($array as $index => $value)
   {
      if(is_numeric($value) && $value > $highest)
      {
          $highest = $index;
      }
   }
   return $highest;
}

echo getHighest($array); //key5

或者,如果做魔法的话,它可能要快于所建的工作场所。

$maxValue = -1;
$max = array();
foreach ($items as $key => $item) {
    if ($item == $maxValue) {
        $max[] = $key;
    } elseif ($item > $maxValue) {
        $max = array();
        $max[] = $key;
        $maxValue = $item;
    }
}
