用於獲取總運輸尺寸的模塊化功能

Question

我目前正在建設的一個站點使用的貨運公司有三種不同的貨盤尺寸可供運輸：最大250公斤，最大500公斤，最大1000公斤。

雖然我已經構建了一個函數來獲取總重量所需托盤的配置，但它是一種硬編碼，我正在尋找一種更加模塊化的方法來處理這個問題，如果我扔另一個托盤重量在以後的日期或爲其他項目使用相同的功能。

什麼我是這樣的：

$sizes = array(
     array('desc'=>'large','limit'=>1000), 
     array('desc'=>'medium','limit'=>500), 
     array('desc'=>'small','limit'=>250) 
     ); 
foreach ($sizes as $k=>$v) { 
    $pallets[$v['desc']] = 0; 
} 

echo $total_weight = 2280; 
echo "<hr />"; 

function pallet_size($weight) { 

    global $sizes, $pallets; 

    if ($weight > $sizes[1]['limit']) { 
     $pallets[$sizes[0]['desc']]+=1; 
     $weight-=$sizes[0]['limit']; 
     pallet_size($weight); 
    } elseif ($weight > $sizes[2]['limit']) { 
     $pallets[$sizes[1]['desc']]+=1; 
     $weight-=$sizes[1]['limit']; 
     pallet_size($weight); 
    } elseif ($weight < $sizes[2]['limit'] && $weight>0) { 
     $pallets[$sizes[2]['desc']]+=1; 
     $weight-=$sizes[2]['limit']; 
     pallet_size($weight); 
    } elseif ($weight<=0) { 
     print_r($pallets); 
     exit(); 
    } 
} 

pallet_size($total_weight); 

也許我只是要對此完全錯誤的方式？

Answer 1

爲什麼不創建一個表格，允許您在將來添加額外的重量信息。只需要查詢數據。通過這種方式，你可以很容易地添加/編輯/刪除權，不具備編輯您的代碼

試試這個代碼：

foreach($sizes as $key => $value){ 

     if($weight > $value[$key]['limit']){ 
      $pallets[$value[$key]['desc'] += 1; 
      $weight -= $value[$key]['limit']; 
      pallet_size($weight); 
     }else if ($weight < $value[$key]['limit']){ 
      $pallets[$value[$key]['desc'] += 1; 
      $weight -= $value[$key]['limit']; 
      pallet_size($weight); 
     }else if ($weight <= 0){ 
      print_r($pallets); 
      exit(); 
     } 

}

我現在已經工作了這一點：

$sizes = array(
      array('desc'=>'large','limit'=>1000), 
      array('desc'=>'medium','limit'=>500), 
      array('desc'=>'small','limit'=>250), 
      array('desc'=>'parcel','limit'=>25) 
      ); 
foreach ($sizes as $k=>$v) { 
    $pallets[$v['desc']] = 0; 
} 

echo $total_weight = 1023; 
echo "<hr />"; 

function pallet_size($weight) { 

    global $sizes, $pallets; 

    for ($i=0;$i<count($sizes);$i++) { 
     if ($i==(count($sizes)-1)) { 
      if ($weight < $sizes[$i]['limit'] && $weight>0) { 
       $pallets[$sizes[$i]['desc']]+=1; 
       $weight-=$sizes[$i]['limit']; 
       pallet_size($weight); 
      } elseif ($weight<=0) { 
       print_r($pallets); 
       exit(); 
      } 
     } else { 
      if ($weight > $sizes[($i+1)]['limit']) { 
       $pallets[$sizes[$i]['desc']]+=1; 
       $weight-=$sizes[$i]['limit']; 
       pallet_size($weight); 
      } elseif ($weight<=0) { 
       print_r($pallets); 
       exit(); 
      } 
     }  
    } 
} 

pallet_size($total_weight);
