I have an array like this:

[5229561]=> 8
[5229582]=> 9
[5229583]=> 10
[5229584]=> 11
etc

我如何能够获得比/等于10的最低限度价值?

So, it this example, it would give me 5229583. I know about the min() function, but I m not sure how to get a value greater than 10.

最佳回答

你们需要为此评估阵列,你们可以采用以下几种方法:

简明扼要(而不是试图虚弱)一例,显示你最容易地在公共卫生和社会福利部学习。

$input_array = array( 5229561  => 8,
                      5229582  => 9,
                      5229583  => 10,
                      5229584  => 11);

foreach ($input_array as $key => $value) {
    if($value >= 10) {
        $output[$key] = $value;
    }
}

产出如下:

array (
       5229583  => 10,
       5229584  => 11
      )

希望

EDIT 添加: (请上下文RiaD员额)

function greaterTen($var) {
    return ($var >= 10);
}

$output = array_filter($input_array,"greaterTen");

甚至(截至 php5.3):

$output = array_filter($input_array,function ($var) {
    return ($var >= 10);
});
问题回答

如果对阵列进行分类,钥匙是连续的(例如100 101 102,078,513),你可以使用双轨搜索。

Overwise you can t do it more quickly than linear search.

《法典》第(1)条增加了记忆的使用:

$curbest=null;
foreach($data as $k => $v){
    if($v>=10 && (is_null($curbest) || $v<$data[$curbest]))
        $curbest=$k;
}

您或许希望对阵列进行分类(使用<条码>sort)。 如果你需要钥匙,那么,在你发现和看上去之前,就会 it;=最低值。

与此类似:

function findMinValueAbove($array, $min)
{
    sort($array);
    foreach ($array as $v) if ($v >= $min) return $v;
}
