Question

我有一个具有混合值的数组，如下所示：

Array
(
 [0] => 93,103
 [1] => 93
 [2] => 103
 [3] => 95,45,93,18
 [4] => 12,45
)

我想将它转换为Array，每个值都是唯一的，如下所示：

Array
(
 [0] => 93
 [1] => 103
 [2] => 18
 [3] => 12
 [4] => 95
 [5] => 45
)

这样做的好方法是什么？

Answer 1

如下所示：

$array = array(
  '93,103',
  '93',
  '103',
  '95,45,93,1',
  '12,45'
);

$result = array_unique(call_user_func_array('array_merge', array_map(function($e) {
  return explode(',', $e);
}, $array)));

var_dump($result);

结果：

array(6) {
  [0]=>
  string(2) "93"
  [1]=>
  string(3) "103"
  [4]=>
  string(2) "95"
  [5]=>
  string(2) "45"
  [7]=>
  string(1) "1"
  [8]=>
  string(2) "12"
}

Answer 2

$yourArray = array(
    '93,103',
    '93',
    '103',
    '95,45,93,18',
    '12,45',
);
$new = array();
foreach ($yourArray as $val) {
    $new = array_merge($new, explode(",", $val));
}
foreach (array_unique($new) as $n){
    $result[] = $n;
}
print_r($result);

你只是使用内爆并爆炸它会对你有用。

$a=Array
(
 [0] => 93,103
 [1] => 93
 [2] => 103
 [3] => 95,45,93,18
 [4] => 12,45
)

$b=implode(",",$a);
$c=explode(",", $b);
$c=Array
(
 [0] => 93
 [1] => 103
 [2] => 18
 [3] => 12
 [4] => 95
 [5] => 45
)
