php - 重组数组以将元素从第三个位置连接到数组末尾并存储为第三个元素

Question

我有这样的数组:

Array(
    [0] => 85
    [1] => 85167920
    [2] => ELECTRICAL/ELECTRONIC
    [3] => DEVICES
    [4] => FOR
    [5] => REPELLING
    [6] => INSECTS
    [7] => (E.G.MOSQUITOES
    [8] => ETC)
)

和

Array(
   [0] => 85
   [1] => 851680
   [2] => ELECTRIC
   [3] => HEATING
   [4] => RESISTORS
)

我想要这样的数组:

Array(
    [0] => 85
    [1] => 851680
    [2] => ELECTRIC HEATING RESISTORS
)

和

Array(
    [0] => 85
    [1] => 85167920
    [2] => ELECTRICAL/ELECTRONIC DEVICES FOR REPELLING INSECTS (E.G.MOSQUITOES ETC)
)

我不确定使用什么方法:合并/组合/推送。
我应该使用什么？

Answer 1

使用array_slice()和implode()

方法:(Demo)

$array=[85,851680,'ELECTRIC','HEATING','RESISTORS'];
$array=[$array[0],$array[1],implode(' ',array_slice($array,2))];
var_export($array);

输出:

array (
  0 => 85,
  1 => 851680,
  2 => 'ELECTRIC HEATING RESISTORS',
)
