在不调用新密钥的情况下将数组添加到现有数组

Question

我正在构建一个3页的提交表单,我非常希望将所有$ _POST结果存储在一个会话变量中.

因此,第1页首先设置数组并添加第一批帖子数据:

$_SESSION['results'] = array();
$_SESSION['results'] = $_POST // first lot of post data

这很好用,返回一个数组,如:

Array
(
  [name] => bob
  [address] => 1 foobar way
  [age] => 100
)

所以当我从第2页获得结果时,我想简单地将它们附加到现有数组而不调用新数组+键

array_push($_SESSION['results'], $_POST); //second lot of post data

得到这样的东西:

Array
(
  [name] => bob
  [address] => 1 foobar way
  [age] => 100
  [job] => rubbish php dev
  [salary] => 1000
)

但相反,我得到:

Array
(
  [name] => bob
  [address] => 1 foobar way
  [age] => 100
  [0] => Array
    (
      [job] => rubbish php dev
      [salary] => 1000
    )
)

更令人讨厌的是,我确信在调整代码之前我已经正常工作了.我究竟做错了什么？

您也可以使用+运营商:

$combined = $_SESSION['results'] + $_POST;
