Question

我知道这很容易思考，但不知道如何将其转换为代码。我有两组数组（标题和正文），如下所示：

HEADER
'tfa_1' => string '(First, Middle, Last)' (length=21)
  'tfa_10' => string 'Card Type' (length=9)
  'tfa_11' => string 'Diners Club' (length=11)
  'tfa_12' => string 'MasterCard' (length=10)
  'tfa_3' => string 'Last 4 Digits of Card Number' (length=28)
  'tfa_127' => string 'Email Address' (length=13)
  'tfa_150' => string 'Phone Number' (length=12)
  'tfa_156' => string 'What type of phone number is this?' (length=34)
  'tfa_157' => string 'Mobile Number' (length=13)
  'tfa_158' => string 'Landline Number' (length=15)
  'tfa_128' => string 'When is the best time to call you for verification?' (length=51) 

BODY
 'tfa_1' => string 'Mike' (length=18)
  'tfa_10' => string 'MasterCard' (length=10)
  'tfa_3' => string '123' (length=4)
  'tfa_127' => string 'mike@yahoo.com' (length=22)
  'tfa_150' => string '09xxxxxx' (length=11)
  'tfa_156' => string 'Mobile Number' (length=13)

我需要它像这样：

 'tfa_1' => string 'mike' (length=21)
      'tfa_10' => string 'MasterCard' (length=9)
      'tfa_11' => string '' (length=11)
      'tfa_12' => string '' (length=10)
      'tfa_3' => string '123' (length=28)
      'tfa_127' => string 'mike@yahoo.com' (length=13)
      'tfa_150' => string 'P09xxxxxx' (length=12)
      'tfa_156' => string 'Mobile Number' (length=34)
      'tfa_157' => string '' (length=13)
      'tfa_158' => string '' (length=15)
      'tfa_128' => string ''

我试过

$merge = (array_merge($header,$body));

成功但我需要那些$ body没有响应的特定键应该为NULL

Answer 1

如果密钥存在，则添加值else填充空值..

$data将满足您的需求。我假设$header是标题数组，$body是主体数组。

  $data=array();  
  foreach($header as $key=>$value){
  if (array_key_exists($key, $body)) 
    $data[key]=$body[$key];
  else
    $data[key]="";
  }

Answer 2

首先你可以使用

如果要转储$arrayMerge = array_merge($array1, $array2);，则它包含重复的值。

您可以使用$arrayMerge

我希望它会对你有所帮助。

数组合并使用循环
