Question

我有一个对象数组＆＃34; $ arr＆＃34;像这样：

Array
(
   [0] => stdClass Object
       (
           [1] => 1
       )

   [1] => stdClass Object
       (
          [0] => 1
       )

   [2] => stdClass Object
       (
          [4] => 2
       )

   [3] => stdClass Object
       (
          [3] => 2
       )

   [4] => stdClass Object
       (
          [2] => 3
       )

)

我想要做的是根据密钥对值进行排名。如果键（$ arr [$ idx + 1]）＆lt; key（$ arr [$ idx]）然后将$ arr [idx]的值增加1.所以结果看起来像：

Array
(
   [0] => stdClass Object
       (
           [1] => 2
       )

   [1] => stdClass Object
       (
          [0] => 1
       )

   [2] => stdClass Object
       (
          [4] => 5
       )

   [3] => stdClass Object
       (
          [3] => 4
       )

   [4] => stdClass Object
       (
          [2] => 3
       )

)

这是我到目前为止所做的：

$arrIdx2=[];
foreach($arrIdx as $key=>$value){
    $newVal = new stdClass();
    $newVal->$key = $value;
    $arrIdx2[] = $newVal;
}

foreach($arrIdx2 as $key=>$value){
   $i= key((array)$value); 
   $m = $value->$i;  //get the first value
   for($j = $key+1; $j< $len; $j++){
       $i2 = key((array)$arrIdx2[$j]); //get the key of second value
       $n = $arrIdx2[$j]->$i2;
       if($n == $m){
          if($i2 < $i){
             $arrIdx2[$key]->$i += 1;
          }
       }
   }
}

这是我得到的结果：

Array
(
    [0] => stdClass Object
        (
            [1] => 2
        )

    [1] => stdClass Object
        (
            [0] => 1
        )

    [2] => stdClass Object
       (
            [4] => 3
       )

    [3] => stdClass Object
       (
            [3] => 2
       )

    [4] => stdClass Object
       (
            [2] => 3
      )

)

最好的方法是什么？谁能指导我？感谢

使用关联数组执行此操作。我无法创建一个对象数组马上。如果您提供对象数组，那么我将更新我的答案。

试试这个：

$arr = array(
            array("1" => 1),
            array("0" => 1),
            array("4" => 2),
            array("3" => 2),
            array("2" => 3)
        );

$out = array();
$first = key(current($arr));
$end =  key(end($arr));
foreach($arr as $key => $val){  
    $comp = (key($val) == $end) ? $end : key($arr[$key+1]);

    if($comp <= key($val))
        $out[$key][key($val)] = key($val) + 1;
    else
        $out[$key][key($val)] = $val[key($val)];
}

echo '<pre>';
print_r($out);

<强>结果

Array
(
    [0] => Array
        (
            [1] => 2
        )

    [1] => Array
        (
            [0] => 1
        )

    [2] => Array
        (
            [4] => 5
        )

    [3] => Array
        (
            [3] => 4
        )

    [4] => Array
        (
            [2] => 3
        )    
)

我想你想要这个，请告诉我。
