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.

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);
});
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条码>)。 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;
}
