PHP 实现桶排序

<?phpfunction Bucket_sort($array){//初始化桶大小$min = min($array);$max = max($array);$book = array_fill($min, $max-$min+1, 0);//将要进行的数据进行计数foreach ($array as $key) {$book[$key]++;// echo $book[$key];}//返回数据$resArr = array();foreach ($book as $key => $value) {for ($i=1; $i <= $value; $i++) { $resArr[] = $key;}}// print_r($resArr);return $resArr;}
$arr = array(8,100,50,22,15,6,1,1000,999,0);
$res = Bucket_sort($arr);
echo implode(',', $res);?>
