PHP关联数组仅显示第一个字母值

I have a HTML form with multiple inputs.

I have the below php code to get them inputs and put them in an associated array.

However, when dumping the Associated array the value only shows the first letter...

<?php
$valueArray=array
(
  "servername"=>'',
  "serverlocation"=>'',
  "servertype"=>'',
  "serverdescription"=>''
);

 foreach($valueArray as $key => $value)
{
  if (isset($_POST[$key]))
  {
   $postValue = $_POST[$key];
   $actualValue = $postValue;
   $valueArray[$key][$value] = $actualValue;
 }
}

var_dump($valueArray);


?> 

This is what is dumped -

array(4) { ["servername"]=> string(1) "d" ["serverlocation"]=> string(1) "K" ["servertype"]=> string(1) "P" ["serverdescription"]=> string(1) "t" } post

How do i get it to store the whole string, and not just the first letter?

If you want to fill the valueArray with the content of the POST request you have to do this:

$valueArray=array
(
  "servername"=>'',
  "serverlocation"=>'',
  "servertype"=>'',
  "serverdescription"=>''
);

 foreach($valueArray as $key => $value)
{
  if (isset($_POST[$key]))
  {
   $postValue = $_POST[$key];
   $valueArray[$key] = $postValue;
 }
}

var_dump($valueArray);

I think you ar wrong with this line:

$valueArray[$key][$value] = $actualValue;

Try this

$valueArray=array
(
  "servername"=>'',
  "serverlocation"=>'',
  "servertype"=>'',
  "serverdescription"=>''
);
$postData=array
(
  "servername"=>'serverName',
  "serverlocation"=>'serverLocation',
  "servertype"=>'serverType',
  "serverdescription"=>'serverDescription'
);
 foreach($valueArray as $key => $value)
{
  if (isset($postData[$key]))
  {
   $postValue = $postData[$key];
   $actualValue = $postValue;
   $valueArray[$key] = $actualValue;
 }
}

var_dump($valueArray);
