    [ufile] => Array

        )

Answer 1

我相信这会清理你的数组：删除空元素（那些评估为空的元素，例如“”和0等），删除重复的元素，然后对其进行排序。

$cleaned = array_map('array_filter', $array_to_be_cleaned);
$cleaned = array_map('array_unique', $cleaned);
$cleaned = array_map('sort', $cleaned);

Answer 2

要过滤掉数组的空元素，请查看array_filter。要对元素进行排序，请查看sort（或参阅此list of sorting functions以查看符合您需求的内容）

$newarray = array_filter($myarray);
sort($newarray);

这将获取您传递的数组（即$myarray），它将删除任何空值，然后将结果存储到$newarray。之后，sort会将剩余的值从最小到最大组织起来。

Answer 3

试试array_filter($array)。它将删除所有NULL元素并返回已清除的数组。

Answer 4

unset( $var['ufile']['type'] );
unset( $var['ufile']['tmp_name'] );

要排序，请使用sort()，usort()或您想要的任何其他内容。这是一个good comparison of the different sort methods。
