マージしたり...私は2の配列を持っていると私はマージしたり、それらを結合したいPHP

Question

でそのキーに基づいて、私は彼らが次のようになりたい

Array 
(
    [0] => Array 
     (
      [year] => 2015 
      [value] => 32 
     ) 

    [1] => Array 
     (
      [year] => 2016 
      [value] => 54 
     )  
) 

Array 
(
    [0] => Array 
     (
      [year] => 2015 
      [value] => 95 
     ) 

    [1] => Array 
     (
      [year] => 2016 
      [value] => 2068 
     ) 

) 

を... 2つの配列を結合する方法

Array(
    [2015]=>array(
     [0] => 32 
     [1] => 95 
    ) 
    [2016]=>array(
     [0] => 54 
     [1] => 2068 
    ) 
) 

これは可能ですか？これまでならば、どのように....本当にありがとうございました

Answer 1

$a = array(
    0 => array 
     (
      "year" => 2015, 
      "value" => 32 
     ), 
    1 => array 
     (
      "year" => 2016, 
      "value" => 54 
     ) 
); 

$b = array(
    0 => array 
     (
      "year" => 2015, 
      "value" => 300 
     ), 
    1 => array 
     (
      "year" => 2016, 
      "value" => 5400 
     ) 
); 

$c = array_merge($a,$b); 

$output = array(); 
foreach($c as $key=>$val) 
{ 
    $output[$val['year']][] = $val['value']; 
} 

echo '<pre>'; 
print_r($output); 
exit; 

これを試してみてくださいコード..

Answer 2

試してみてください。？元の配列が$aと$bある場合

$newArr = array(); 
foreach($array1 as $key1=>$arr1) { 
    $newArr[$arr1['year']][] = $arr1['value']; 
    $newArr[$arr1['year']][] = $array2[$key]['value']; 
} 

Answer 3

は、このコードを実行すると、あなたが望む結果が$result

$sources = array_merge($a,$b); 
$result = []; 
foreach($sources as $data){ 
    $yr = $data['year']; 
    if(!isset($result[$yr])) $result[$yr]=[]; 
    $result[$yr][]=$data['value']; 
} 

になります

Answer 4

ます。また、このような何かを行うことができ、

<?php 
$test1 = [["year"=>2015,"value"=>32],["year"=>2016,"value"=>54]]; 
$test2 = [["year"=>2015,"value"=>95],["year"=>2016,"value"=>2068]]; 

$newarray=array(); 
foreach($test1 as $key1=>$value1){ 
    $temp = [$value1['value']]; 
    foreach($test2 as $key2=>$value2){ 
    if($value1['year']==$value2['year']){ 
    $temp[] = $value2['value']; 
    } 
    $newarray[$value1['year']] = $temp; 
    } 
} 

print_r($newarray); 
?>

出力は、次のとおりです。[PHPの

Array 
(
    [2015] => Array 
     (
      [0] => 32 
      [1] => 95 
     ) 

    [2016] => Array 
     (
      [0] => 54 
      [1] => 2068 
     ) 

)
