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。

$max = max(array_values($array));
$keys = array_keys($array, $max);
$array = array(
key1 => 22,
key2 => 17,
key3 => 19,
key4 => 21,
key5 => 24,
key6 => 8,
);
function getHighest($array)
{
$highest = 0;
foreach($array as $index => $value)
{
if(is_numeric($value) && $value > $highest)
{
$highest = $index;
}
}
return $highest;
}
echo getHighest($array); //key5
