Question

我有我的数据数组，通过将每个循环使用的键拆分为，将其转换为json。

数据：

        "samt":0,
        "iamt":0,
        "csamt":0
     }
  ]
   }
}

我下一步要做的是取消设置json的键或整个内部对象。

请记住以下条件：


1。如果对象中的所有键均为0，则将删除整个对象（容易的部分）。

2。如果对象中的键具有除0之外的任何其他值，则不应删除该对象，并且值“ 0”的键也应位于该位置。

我尝试过分割值并使用条件检查0或null值，但是问题在于它会删除所有具有0值的键，从而使代码的条件2失败。

   $vars = $data;
   $count = "";
   $finalArray = array();
   foreach ($vars as $keys => $values) {
     foreach ($values as $k => $v) {
       foreach ($v as $ke => $ve) {
               if ($keys == "table6") {
                  $count = (array)$v;    
                  foreach ($count as $ck => $cv) {
                    if ($cv != "0")
                    {
                     $flag = true;
                     break;
                    }
                  }

         if($flag == false)
              {
                array_push($finalArray, $count);
              }                         
       }
    }
 }
print_r($finalArray);
die();

我期望输出包含键值对的对象，这些键值对不包含0值，但是所有内容都在此处打印。

Answer 1

我认为问题在于您试图以相同的方式处理不同级别的值，ios具有一组数值，因此需要直接处理，但是iog等有一组嵌套的数组。我注意到，在您的内部数组中，您似乎正在检查来自较高一级循环的数据，而不是当前循环中的数据...

   foreach ($v as $ke => $ve) {
       if ($keys == "table6") {
           $count = (array)$v;

您的循环值为$ve，但您正在检查$v。

尽管这可能不如处理该问题那么优雅，但基本上，它将找到需要检查的所有相关项目，并使用array_sum()将所有值加起来，如果结果> 0，然后将数据（具有适当的结构）复制到整个...

$vars = $data;
$finalArray = array();
foreach ($vars as $keys => $values) {
    foreach ($values as $k => $v) {
        // Check if this also has sub-arrays
        if ( is_array($v[array_keys($v)[0]] ))   {
            foreach ($v as $k1 => $v1) {
                if ( array_sum($v1) > 0 )    {
                    $finalArray[$keys][$k][$k1] = $v1;
                }
            }
        }
        if ( array_sum($v) > 0 )    {
            $finalArray[$keys][$k] = $v;
        }
    }
}
print_r($finalArray);

Answer 2

我认为递归方法在这里更好-如：

function removeAllZero(&$arr) {
    foreach($arr as $k => &$e) {
        if (is_array($e) && removeAllZero($e)) // if array goes and all zero
            unset($arr[$k]); // remove it 
        else if ($e != 0) return false; // there are non-zero 
    } 
    return true; 
}
