清除php空数组

Question

我有以下数组，我想摆脱/删除空数组，并在order.can中重新排列它，有人能帮我吗？

Array

    [ufile] => Array
        (

            [name] => Array
                (
                    [0] => chicken soup.jpg
                    [1] => 
                    [2] => hot n sour sup.jpg
                    [3] => 
                    [4] => 
                    [5] => 
                    [6] => 
                    [7] => 
                    [8] => 
                )

            [type] => Array
                (
                    [0] => 
                    [1] => 
                    [2] => 
                    [3] => 
                    [4] => 
                    [5] => 
                    [6] => 
                    [7] => 
                    [8] => 
                )

            [tmp_name] => Array
                (
                    [0] => 
                    [1] => 
                    [2] => 
                    [3] => 
                    [4] => 
                    [5] => 
                    [6] => 
                    [7] => 
                    [8] => 
                )

            [error] => Array
                (
                    [0] => 1
                    [1] => 4
                    [2] => 1
                    [3] => 4
                    [4] => 4
                    [5] => 4
                    [6] => 4
                    [7] => 4
                    [8] => 4
                )

            [size] => Array
                (
                    [0] => 0
                    [1] => 0
                    [2] => 0
                    [3] => 0
                    [4] => 0
                    [5] => 0
                    [6] => 0
                    [7] => 0
                    [8] => 0
                )

        )

)

Answer 1

我相信这将清理您的数组:删除空元素(那些计算结果为空的元素，例如"“和0)，删除重复的元素，并对其进行排序。

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

Answer 2

要过滤掉数组中的空元素，请查看array_filter。要对元素进行排序，请查看sort (或参考此list of sorting functions以了解哪些元素满足您的需求)

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

这将接受您传递的数组(即.$myarray)，它将去掉所有空值，然后将结果存储到$newarray中。在此之后，排序将按照从小到大的顺序组织剩余的值。

Answer 3

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