Question

我有这个数组：

array(9) {
    [0]=>
    string(5) ",103,"
    [1]=>
    string(4) ",12,"
    [2]=>
    string(5) ",123,"
    [3]=>
    string(5) ",135,"
    [4]=>
    string(5) ",148,"
    [5]=>
    string(4) ",27,"
    [6]=>
    string(16) ",30,31,38,39,40,"
    [7]=>
    string(4) ",35,"
    [8]=>
    string(4) ",94,"
}

如何将它合并到这样的数组？

$a = array(12, 27, 30, 31, 35, 38, 39, 40, ...)

我试过但却毫无头绪......

Answer 1

使用sort和$arr = [",103,",",12,",",123,",",135,",",148,",",27,",",30,31,38,39,40,",",35,",",94,"]; preg_match_all('/\d+/', implode("", $arr), $m); $result = $m[0]; sort($result); print_r($result);函数的解决方案：

Array
(
    [0] => 12
    [1] => 27
    [2] => 30
    [3] => 31
    [4] => 35
    [5] => 38
    [6] => 39
    [7] => 40
    [8] => 94
    [9] => 103
    [10] => 123
    [11] => 135
    [12] => 148
)

输出：

tabindex="-1"

Answer 2

<?php
$test = array(",103,", ",12,", ",123,", ",135,", ",148,", ",27,",",30,31,38,39,40,", ",35,", ",94,");

$values = array_filter(explode(',', implode(",", $test)));
sort($values);
print_r($values);

将所有值内容压缩为一个字符串
转换为数组
删除空值
排序

将输出

Array
(
    [0] => 12
    [1] => 27
    [2] => 30
    [3] => 31
    [4] => 35
    [5] => 38
    [6] => 39
    [7] => 40
    [8] => 94
    [9] => 103
    [10] => 123
    [11] => 135
    [12] => 148
)

Answer 3

你可以遍历数组，然后用逗号分解它。然后，如果该值不是空的sting，则将其添加到新数组。

$arr = [",103,", ",12,", ",123,", ",135,", ",148,", ",27,", ",30,31,38,39,40,", ",35,", ",94,"];
$new = array();

foreach ($arr as $val) {
  foreach (explode(",", $val) as $char) {
      if ($char != '') {
        array_push($new, $char);
      }
    }
  }

Answer 4

试试这个：

sort(explode(',', str_replace(',,', ',', implode('', $a))));
