多次元配列を単純な配列に分割する方法

Question

私は多次元配列を持っています。これはユーザーの選択リストです。これは、ユーザーから取得したデータの単なる例です。サブアレイの組み合わせは、ユーザの選択によって変わることがあります。 要素3,5,2をそれぞれ有する3つのサブ配列に似ている。そして、配列のキーは、そのからのものにする必要があります...

array(7) { 
    ["resume_residence"]=> 
    string(8) "Barbados" 
    ["resume_language_fluently"]=> 
    string(8) "Mandarin" 
    ["resume_language_professional"]=> 
    string(7) "Spanish" 
    ["resume_language_basic"]=> 
    string(8) "Mandarin" 
    ["resume_overseas_experience"]=> 
    string(2) "No" 
    ["resume_degree"]=>  array(2) { 
     [0]=> string(2) "BA" 
     [1]=> string(3) "BFA" 
    } 
    ["resume_career_employment_status"]=> array(2) { 
     [0]=> string(8) "Employed" 
     [0]=> string(10) "Unemployed" 
    } 
} 

を、私はどのように私を助けてください

array(4){ 
    array(7) { 
     ["resume_residence"]=> string(8) "Barbados" 
     ["resume_language_fluently"]=> string(8) "Mandarin" 
     ["resume_language_professional"]=> string(7) "Spanish" 
     ["resume_language_basic"]=> string(8) "Mandarin" 
     ["resume_overseas_experience"]=> string(2) "No" 
     ["resume_degree"]=> string(2) "BA" 
     ["resume_career_employment_status"]=> string(2) "Employed" 
    }, 
    array(7) { 
     ["resume_residence"]=> string(8) "Barbados" 
     ["resume_language_fluently"]=> string(8) "Mandarin" 
     ["resume_language_professional"]=> string(7) "Spanish" 
     ["resume_language_basic"]=> string(8) "Mandarin" 
     ["resume_overseas_experience"]=> string(2) "No" 
     ["resume_degree"]=> string(2) "BA" 
     ["resume_career_employment_status"]=> string(2) "Unemployed" 
    }, 
    array(7) { 
     ["resume_residence"]=> string(8) "Barbados" 
     ["resume_language_fluently"]=> string(8) "Mandarin" 
     ["resume_language_professional"]=> string(7) "Spanish" 
     ["resume_language_basic"]=> string(8) "Mandarin" 
     ["resume_overseas_experience"]=> string(2) "No" 
     ["resume_degree"]=> string(2) "BFA" 
     ["resume_career_employment_status"]=> string(2) "Employed" 
    }, 
    array(7) { 
     ["resume_residence"]=> string(8) "Barbados" 
     ["resume_language_fluently"]=> string(8) "Mandarin" 
     ["resume_language_professional"]=> string(7) "Spanish" 
     ["resume_language_basic"]=> string(8) "Mandarin" 
     ["resume_overseas_experience"]=> string(2) "No" 
     ["resume_degree"]=> string(2) "BFA" 
     ["resume_career_employment_status"]=> string(2) "Unemployed" 
    } 
} 

よう変換するために、それぞれが単一の値のキーを持つ複数のアレイにこの配列をしたいです上記のように配列を複数の配列に分割することができます。

Answer 1

入力の異なるキーに割り当てられた配列値のすべての可能な組み合わせを生成すると思われるようです。

あなたは再帰でこれを行うことができます。

$array = [ 
    "resume_residence"=> "Barbados", 
    "resume_language_fluently"=> "Mandarin", 
    "resume_language_professional"=> "Spanish", 
    "resume_language_basic"=> "Mandarin", 
    "resume_overseas_experience"=> "No", 
    "resume_degree"=> ["BA", "FBA"], 
    "resume_career_employment_status"=> ["Employed", "Unemployed"] 
]; 

function expandArrays(&$array) { // Argument by reference 
    // Get current key and value based on the array pointer 
    $key = key($array); 
    $value = current($array); 
    // Get results for any further key/values through recursion: 
    $results = next($array) ? expandArrays($array) : [$array]; 
    // Nothing changes if the current value is not an array 
    if (!is_array($value)) return $results; 
    // It is an array, so produce all combinations of the partial results with each value 
    foreach($value as $v) { 
     foreach($results as $r) { 
      $r[$key] = $v; 
      $newResults[] = $r; 
     } 
    } 
    // ... and return that as a result 
    return $newResults; 
} 

$results = expandArrays($array); 

print_r($results);
