foreachを常に数回繰り返します

Question

私はいつも12 $new['period_??']を持っています。今のところ、$new['period_??']と宣言してから12回これらのコードを書いています。簡単にする方法はありますか？

  foreach ($new ['period_10'] as $item) { $po_10th [] = $item -> po_id ; } 
      $new ['uni_10'] = array_unique($po_10th) ; 
      foreach ($new ['uni_10'] as $po_id) { 
      $po = $this -> model_prcsys -> get_po_by_id (md5($po_id)) ; 
      $pos_10 [] = $po ['po_id'] ; 
      $currency10 [] = $po ['currency'] ; 
      } 
      $cur_pos_10 = array_unique($currency10) ; 
      foreach ($cur_pos_10 as $currency) { 
      $new ['po_arr_10'] = $this -> model_prcsys -> get_pos_with_curr ($pos_10,$currency) ; 
      $total_price = array() ; 
      $curren = array() ; 
       foreach ($new ['po_arr_10'] as $key) { 
       $total_price [] = $key -> total_line_price ; 
       $curren [] = $key -> currency ; 
       } 
       $new ['total_n_curr10'] [] = array_merge(array(array_sum($total_price)),array_unique($curren)) ; 
      } 

これは私がやった難しい現実です！

$new ['period_1'] = $periodic_items [0] ; $new ['frek_1'] = $frek [0] ; 
     $new ['period_2'] = $periodic_items [1] ; $new ['frek_2'] = $frek [1] ; 

     $new ['period_3'] = $periodic_items [2] ; $new ['frek_3'] = $frek [2] ; 
     $new ['period_4'] = $periodic_items [3] ; $new ['frek_4'] = $frek [3] ; 

     $new ['period_5'] = $periodic_items [4] ; $new ['frek_5'] = $frek [4] ; 
     $new ['period_6'] = $periodic_items [5] ; $new ['frek_6'] = $frek [5] ; 

     $new ['period_7'] = $periodic_items [6] ; $new ['frek_7'] = $frek [6] ; 
     $new ['period_8'] = $periodic_items [7] ; $new ['frek_8'] = $frek [7] ; 

     $new ['period_9'] = $periodic_items [8] ; $new ['frek_9'] = $frek [8] ; 
     $new ['period_10'] = $periodic_items [9] ; $new ['frek_10'] = $frek [9] ; 
     foreach ($new ['period_10'] as $item) { $po_10th [] = $item -> po_id ; } 
      $new ['uni_10'] = array_unique($po_10th) ; 
      foreach ($new ['uni_10'] as $po_id) { 
      $po = $this -> model_prcsys -> get_po_by_id (md5($po_id)) ; 
      $pos_10 [] = $po ['po_id'] ; 
      $currency10 [] = $po ['currency'] ; 
      } 
      $cur_pos_10 = array_unique($currency10) ; 
      foreach ($cur_pos_10 as $currency) { 
      $new ['po_arr_10'] = $this -> model_prcsys -> get_pos_with_curr ($pos_10,$currency) ; 
      $total_price = array() ; 
      $curren = array() ; 
       foreach ($new ['po_arr_10'] as $key) { 
       $total_price [] = $key -> total_line_price ; 
       $curren [] = $key -> currency ; 
       } 
       $new ['total_n_curr10'] [] = array_merge(array(array_sum($total_price)),array_unique($curren)) ; 
      } 

     $new ['period_11'] = $periodic_items [10] ; $new ['frek_11'] = $frek [10] ; 
     $new ['period_12'] = $periodic_items [11] ; $new ['frek_12'] = $frek [11] ; 

誰でも簡単にできますか？常に12回ループします...

https://eval.in/670429 ちょうどあなたが望むキーを作ってください。

<?php 
for($i = 0; $i < 10; $i++) 
{ 
$new ['period_'.$i] = $periodic_items [$i]; 
} 
var_dump($new);
