どのように配列のPHPで深いキーを取得するには？

Question

配列している場合：

Array 
(
    [1-title1] => Array 
     (
      [0] => title = title erer 
      [1] => 1-title1 
      [2] => content = content 1 
     ) 

    [2-title2] => Array 
     (
      [0] => title = title dffgfghfdg 
      [1] => 2-title2 
      [2] => content = content 2 
     ) 

を、私は配列を取得したい：

Array 
(
    [1-title1] => Array 
     (
      [title] =>title erer 
      [1] =>title1 
      [content] =>content 1 
     ) 

    [2-title2] => Array 
     (
      [title] =>title dffgfghfdg 
      [2] => title2 
      [content] =>content 2 
     ) 

私は何をすべきか？

Answer 1

は言及していない暗黙のキー名なしでこの

foreach($array as $ky=>$val) { 
    echo $ky; 
    var_dump(array_keys($val)); 
} 

Answer 2

foreach($array as &$title){ 
    $newTitle = array(); 
    $titleName = explode(' = ', $title[0] , 2); 
    $newTitle['title'] = end($titleName); 
    $titleNum = explode('-', $title[1] , 2); 
    $newTitle[$titleNum[0]] = $titleNum[1]; 
    $titleContent = explode(' = ', $title[2] , 2); 
    $newTitle['content'] = end($titleContent); 
    $title = $newTitle; 
} 

Answer 3

ソリューションを試してみてください。

foreach ($array as $key => $innerArray) { 
    foreach ($innerArray as $innerKey => $value) { 
     if (false !== strpos($value, ' = ')) { 
      unset($array[$key][$innerKey]); 
      list($innerKey, $value) = explode(' = ', $value, 2); 
      $array[$key][$innerKey] = $value; 
     } 
    } 
}
