在數組上值合併

我有一個場景，我從兩個單獨的文件 - .xml文件和.txt文件中獲取數據 - 我嘗試使用PHP將2個數組（每個文件一個）組合在一個匹配值從每個。在數組上值合併

我沒有對上述文件的格式控制，因此使用下面的代碼到目前爲止，我已經把：

<?php 
function dir_to_array($dir, $se) { 

    $result = array(); 
    $cdir = scandir($dir); 

    foreach ($cdir as $key => $value) { 

     $file_info = pathinfo($value); 

     if (! in_array($value, array(".", ".."))) { 
      if (is_dir($dir . DIRECTORY_SEPARATOR . $value)) { 

       $result[$value] = dir_to_array($dir . DIRECTORY_SEPARATOR . $value); 

      } else { 

       if ($file_info['extension'] == 'xml') { 

        if (isset($se) && $se !== 'undefined') { 
         if (strpos($value, $se) !== false) { 

          $result['xml'] = xmlToArray(file_get_contents($dir.'/'.$value)); 

         } 
        } 
       } 

       if ($file_info['extension'] == 'txt') { 

        $file = fopen($dir.'/'.$value, 'r'); 
        $count = 0; 

        while (($line = fgetcsv($file)) !== FALSE) { 
         // trying to match the structure of the above array ($result['xml']) 
         $result['txt']['records']['PositionRecords']['record'][$count++] = $line; 
        } 

        fclose($file); 
       } 

      } 
     } 
    } 

    return json_encode($result); 
} 

echo dir_to_array('path/to/something', $arg);

我能夠得到以下陣列：

陣列1：_.XML

[records] => Array 
(
    [PositionRecord] => Array 
    (
     [record] => Array 
     (
      [0] => Array 
      (
       [keyword] => "something", // Value to match 
       [position] => "1" 
      ), 
      ... 
     ) 
    ) 
)

陣列2：_.TXT

[records] => Array 
(
    [PositionRecord] => Array 
    (
     [record] => Array 
     (
      [0] => Array 
      (
       [0] => "something", // Value to match 
       [1] => "1000" 
      ), 
      ... 
     ) 
    ) 
)

如何將加入關於匹配keyword值這些陣列以最終獲得一個這樣的數組：

[records] => Array 
(
    [PositionRecord] => Array 
    (
     [record] => Array 
     (
      [0] => Array 
      (
       [keyword] => "something", 
       [position] => "1", 
       [volume] => "1000" 
      ), 
      ... 
     ) 
    ) 
)

我已經使用array_merge試圖，array_merge_recursive和array_combine但是他們似乎只是將一個數組添加到另一個數組中。我也嘗試過this answer和this answer，它們都返回一個空數組[]。

手動合併這些陣列：

<?php 

$a['records']['PositionRecord']['record'][0] = ['keyword'=>"something","position"=>"1"]; 
$a['records']['PositionRecord']['record'][1] = ['keyword'=>"something2","position"=>"2"]; 
$b['records']['PositionRecord']['record'][0] = ["something","1000"]; 
$b['records']['PositionRecord']['record'][1] = ["something2","2000"]; 


for($i = 0, $c = count($a['records']['PositionRecord']['record']); $i < $c; $i ++) 
{ 
    $a['records']['PositionRecord']['record'][$i]['volume'] = $b['records']['PositionRecord']['record'][$i][1]; 
} 

echo "<pre>"; 
var_dump($a); 
echo "</pre>";

輸出：

array(1) { 
    ["records"]=> 
    array(1) { 
    ["PositionRecord"]=> 
    array(1) { 
     ["record"]=> 
     array(2) { 
     [0]=> 
     array(3) { 
      ["keyword"]=> 
      string(9) "something" 
      ["position"]=> 
      string(1) "1" 
      ["volume"]=> 
      string(4) "1000" 
     } 
     [1]=> 
     array(3) { 
      ["keyword"]=> 
      string(10) "something2" 
      ["position"]=> 
      string(1) "2" 
      ["volume"]=> 
      string(4) "2000" 
     } 
     } 
    } 
    } 
}
