PHP - 関数の戻り値の問題と多次元配列

-2

私は次の問題を持って、私はこの多次元配列があります。またPHP - 関数の戻り値の問題と多次元配列

Array

を、私は以下の機能を持っている：

public function transformValue($array = [], $level = 1) { 
    $return = []; 
    foreach($array as $key => $value){ 
     if(is_array($value)){ 
      $this->transformValue($value, $level + 1); 
     } else{ 
      $return[$key] = $value; 
     } 
    } 
    return $return; 

}

この機能は、受信このマルチ配列をパラメータとして、次のように正規化する必要があります。

私の問題：関数を呼び出して変数に代入すると、関数は変数に値を代入していないように見えますが、print_r（）で関数の戻り値を確認すると、必要な値が表示されます。私はものをスキップする必要があり、私は継続するために "プッシュ"が必要です。これは、関数の戻り値を持つ変数を宣言し、このようにしている：

$return_value_function = []; 
$return_value_function = $this->transformValue($array_values);

変数$ return_value_functionは、関数の戻り値を保存しません。私のミスはどこですか？

'ます$ this-> transformValue（$値、$レベル+ 1）;'何を返し、どのような変数に？ –

私は '$ level'が何のために使われているのか分かりません。 – Chay22

@ Chay22 $レベルは配列の深さを決定するために使用され、関数は再帰的です。 – Ale

あなたはこの呼び出しから値を割り当てる必要があります：変数へ

$this->transformValue($value, $level + 1);

。同様に：この関数が再帰的に呼び出され

$return[$key] = $this->transformValue($value, $level + 1);

毎回は、return文はそれがデータを返さ保持するためには何もないバック&データを送信します。

SOLUTION

再帰なしで同じ出力を達成&次のようにあなたの機能を変更することができます。

function transformValue($array = []) { 
$return = []; 
foreach($array as $key => $value) { 
    if(is_array($value)) { 
     $return = array_merge($return, $value); 
    } 
} 
return $return; 
}

出力は次のようになります。

私のサンプルの配列をのみますのでご注意くださいその2つのキーが含まれています。

そして、この出力は、次のコードを返されます。

$return_value_function = []; 
$return_value_function = transformValue($arr); 
echo '<pre>';print_r($return_value_function);echo '</pre>';

ありがとうございますが、問題は機能ではありません。関数の戻り前にprint_r（$ return）を呼び出すと値が正しく表示されますが、変数$ return_value_functionは関数によって返された値を使用しません。 – Ale

更新されたソリューションを投稿しました。 – tovishalck

ありがとう、これは私のソリューションです!!!! – Ale

以下のコードを参照してください。配列を返します。

public function transformValue($array) {   
    foreach($array as $subarray){ 
     foreach($subarray as $value){ 
      $finalArray[] = $value; 
     } 
    } 
    return $finalArray; 

} 

$finalArray= $this->transformValue($array_values); 
echo "<pre>"; 
print_r($finalArray);
