Php 如何以相同的键将值从一个数组附加到另一个数组？

我有以下两个数组

首先

第二

Array
(
    [45712] => SLF-8480-252-256-508 == 23775
    [45713] => SLF-8480-050 == 17221
    [45714] => SLF-8480-010 == 17217
    [45715] => SLF-8480-030 == 17218
    [45716] => SLF-8480-037 == 17219
)

我想要像这样的输出

Array
(
    [45712] => SLF-8480-252-256-508 == 23775 En Vogue Queen Upholstered Bed == 1675
    [45713] => SLF-8480-050 == 17221 == En Vogue  Nightstand == 1315
    [45714] => SLF-8480-010 == 17217 == En Vogue  Drawer Dresser == 1719
    [45715] => SLF-8480-030 == 17218 == Mirror == 1225
    [45716] => SLF-8480-037 == 17219 == Floor Mirror  == 1349
)

我怎样才能做到这一点呢？

像这样的方法可以奏效

$new_arr = array();
foreach($yoursecondarr as $k=$v)
{
$new_arr[$k]=$v." ".$yourfirstarr[$k];
}
print_r($new_arr);

像这样的东西会有用的

$new_arr = array();
foreach($yoursecondarr as $k=$v)
{
$new_arr[$k]=$v." ".$yourfirstarr[$k];
}
print_r($new_arr);

输出：

Array
(
    [45712] => SLF-8480-252-256-508 == 23775 == En Vogue Queen Upholstered Bed == 1675
    [45713] => SLF-8480-050 == 17221 == En Vogue  Nightstand == 1315
    [45714] => SLF-8480-010 == 17217 == En Vogue  Drawer Dresser == 1719
    [45715] => SLF-8480-030 == 17218 == En Vogue  Mirror == 1225
    [45716] => SLF-8480-037 == 17219 == En Vogue  Floor Mirror  == 1349
)

输出：

    [45712] => SLF-8480-252-256-508 == 23775 == En Vogue Queen Upholstered Bed == 1675

    [45716] => SLF-8480-037 == 17219 == En Vogue  Floor Mirror  == 1349
)

您可以使用以下代码：

foreach ($first_array as $key => $value) {
  if (isset($second_array[$key]) {
    $second_array[$key] = ' ' . $value; 
  } else {
    $second_array[$key] = $value;
  }
}
print_r($second_array);

您可以使用以下代码：

foreach ($first_array as $key => $value) {
  if (isset($second_array[$key]) {
    $second_array[$key] = ' ' . $value; 
  } else {
    $second_array[$key] = $value;
  }
}
print_r($second_array);
