自定義陣列結構

Question

如何轉換以下數組

Array 
(
    [0] => Array 
     (
      [order_num] => 1400236903 
      [status] => unpaid 
      [payment_rec_date] => 2014-05-16 
      [description] => 
      [actual_amount] => 200 
      [stax] => 20.00 
      [stax_value] =>30.00 
      [ed_tax] => 31.21 
      [ed_tax_value] => 30.00 
      [w_ed_tax] => 25.00 
      [w_ed_tax_value] => 55.56 
      [amount] => 12000 
      [total_discount] => 152 
     ) 
    [0] => Array 
     (..... 
     ) 
) 

into 

Array 
(
    [0] => Array 
     (
      [order_num] => 1400236903 
      [status] => unpaid

      [description] => 
      [actual_amount] => 200 
     [data] => {"stax":20.00, "stax_value":30.00,"ed_tax":31.21,"ed_tax_value":30.00,"w_ed_tax":25.00..... } 
     ) 
) 

Answer 1

你可以簡單地做，使用內 array_walk() foreach。這可能會給你你想要的結果。第1部分：算法 - 沒有樣本數組。 （ Quick Test it Here.）

<?php 

    $arrResult = array(); //$arr IS THE MAIN ARRAY TO CLEAN UP 
    $arrFin  = array_walk($arr, function($data, $index) use (&$arrResult){ 
     $clone  = $data; 
     $sifts  = array('stax', 'stax_value', 'ed_tax', 'ed_tax_value', 'w_ed_tax', 'w_ed_tax_value', 'amount', 'total_discount'); 
     $tempObj = new stdClass(); 
     foreach($clone as $k=>$v){ 
      if(in_array($k, $sifts)){ 
       unset($clone[$k]); 
       $tempObj->$k = $v; 
      } 
     } 
     $clone['data'] = $tempObj; 
     $arrResult[] = $clone; 
    }); 

    var_dump($arrResult); 

第2部分：算法 - 與試樣陣列（ Quick Test it Here.）

<?php 

    $arr  = array(
     array(
      'order_num'   =>1400236903, 
      'status'   => 'unpaid', 
      'payment_rec_date' => '2014-05-16', 
      'description'  => null, 
      'actual_amount'  => 200, 
      'stax'    => 20.00, 
      'stax_value'  => 30.00, 
      'ed_tax'   => 31.21, 
      'ed_tax_value'  => 30.00, 
      'w_ed_tax'   => 25.00, 
      'w_ed_tax_value' => 55.56, 
      'amount'   => 12000, 
      'total_discount' => 152, 
     ), 

     array(
      'order_num'   =>3098786903, 
      'status'   => 'paid', 
      'payment_rec_date' => '2014-05-16', 
      'description'  => "Lorem Ipsum", 
      'actual_amount'  => 200, 
      'stax'    => 20.00, 
      'stax_value'  => 30.00, 
      'ed_tax'   => 31.21, 
      'ed_tax_value'  => 30.00, 
      'w_ed_tax'   => 25.00, 
      'w_ed_tax_value' => 55.56, 
      'amount'   => 12000, 
      'total_discount' => 152, 
     ), 
    ); 

    $arrResult = array(); 
    $arrFin  = array_walk($arr, function($data, $index) use (&$arrResult){ 
     $clone  = $data; 
     $sifts  = array('stax', 'stax_value', 'ed_tax', 'ed_tax_value', 'w_ed_tax', 'w_ed_tax_value', 'amount', 'total_discount'); 
     $tempObj = new stdClass(); 
     foreach($clone as $k=>$v){ 
      if(in_array($k, $sifts)){ 
       unset($clone[$k]); 
       $tempObj->$k = $v; 
      } 
     } 
     $clone['data'] = $tempObj; 
     $arrResult[] = $clone; 
    }); 

var_dump($arrResult); 

的 的var_dump（$ arrResult）以上產生下面下面的輸出：（ Quick Test it Here.）

array (size=2) 
     0 => 
     array (size=6) 
      'order_num' => int 1400236903 
      'status' => string 'unpaid' (length=6) 
      'payment_rec_date' => string '2014-05-16' (length=10) 
      'description' => null 
      'actual_amount' => int 200 
      'data' => 
      object(stdClass)[2] 
       public 'stax' => float 20 
       public 'stax_value' => float 30 
       public 'ed_tax' => float 31.21 
       public 'ed_tax_value' => float 30 
       public 'w_ed_tax' => float 25 
       public 'w_ed_tax_value' => float 55.56 
       public 'amount' => int 12000 
       public 'total_discount' => int 152 
     1 => 
     array (size=6) 
      'order_num' => int 3098786903 
      'status' => string 'paid' (length=4) 
      'payment_rec_date' => string '2014-05-16' (length=10) 
      'description' => string 'Lorem Ipsum' (length=11) 
      'actual_amount' => int 200 
      'data' => 
      object(stdClass)[3] 
       public 'stax' => float 20 
       public 'stax_value' => float 30 
       public 'ed_tax' => float 31.21 
       public 'ed_tax_value' => float 30 
       public 'w_ed_tax' => float 25 
       public 'w_ed_tax_value' => float 55.56 
       public 'amount' => int 12000 
       public 'total_discount' => int 152 

Answer 2

你必須使用一個foreach並選中要使用的密鑰。 我使用json_encode()來編碼您的數據。

解決方案：

<?php 

$array = array(
    'order_num' => 1400236903, 
    'status' => 'unpaid', 
    'payment_rec_date' => '2014-05-16', 
    'description' => '', 
    'actual_amount' => 200 , 
    'stax' => 20.00, 
    'stax_value' =>30.00 , 
    'ed_tax' => 31.21, 
    'ed_tax_value' => 30.00, 
    'w_ed_tax' => 25.00, 
    'w_ed_tax_value' => 55.56 , 
    'amount' => 12000, 
    'total_discount' => 152 
); 


$newArray = array(); 
$data = new stdClass(); 

foreach($array as $key => $value) 
{ 
    switch ($key){ 
     case 'order_num': 
     case 'status': 
     case 'payment_rec_date': 
     case 'description': 
     case 'description': 
      $newArray[$key] = $value; 
      break; 
     default: 
      $data->$key = $value; 
    } 
} 
$newArray['data'] = json_encode($data); 

print_r($newArray);
