用于获取总运输尺寸的模块化功能

Question

我目前正在建设的一个站点使用的货运公司有三种不同的货盘尺寸可供运输：最大250公斤，最大500公斤，最大1000公斤。

虽然我已经构建了一个函数来获取总重量所需托盘的配置，但它是一种硬编码，我正在寻找一种更加模块化的方法来处理这个问题，如果我扔另一个托盘重量在以后的日期或为其他项目使用相同的功能。

什么我是这样的：

$sizes = array(
     array('desc'=>'large','limit'=>1000), 
     array('desc'=>'medium','limit'=>500), 
     array('desc'=>'small','limit'=>250) 
     ); 
foreach ($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); 

也许我只是要对此完全错误的方式？

Answer 1

为什么不创建一个表格，允许您在将来添加额外的重量信息。只需要查询数据。通过这种方式，你可以很容易地添加/编辑/删除权，不具备编辑您的代码

试试这个代码：

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(); 
     } 

}

我现在已经工作了这一点：

$sizes = array(
      array('desc'=>'large','limit'=>1000), 
      array('desc'=>'medium','limit'=>500), 
      array('desc'=>'small','limit'=>250), 
      array('desc'=>'parcel','limit'=>25) 
      ); 
foreach ($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);
