php - 重新排列 php 数组；将索引设置为数组值

Question

我有一个数组，我添加到这篇文章的末尾。我需要将数组的“父”值设置为父数组索引号。与父数组 idnumber 值相关的数组父值。

例如;

[131] => Array
    (
        [idnumber] => 171
        [name] => 9f146bfd1b1aa02612b95a0ae7b52f13
        [parent] => 21
    )

父数组

[15] => Array
    (
        [idnumber] => 21
        [name] => 175d60205b36459d75d1cdda406f1ea4
        [parent] => 0
    )

所以新数组；

[131] => Array
    (
        [idnumber] => 171
        [name] => 9f146bfd1b1aa02612b95a0ae7b52f13
        [parent] => 15
    )

但对我来说这个问题的困难部分；idnumbers 必须是唯一的，但前 22 个数组（其父值为 0） idnumbers 可以在其余数组 idnumber 中找到（不多）。这对我来说很难解决这个问题。我尝试了不同的方法，但每种方法都没有效率如我所愿。

这是一个假设如果 anidnumber出现不止一次，则父级将仅引用第一次出现的解决方案。

// create a list of the indexes's for each idnumber
$convert_list=array(); // initialise array
reset($data); // pointer to start
while(list($index,$datum)=each($data)) // loop through data
{
    $idnumber=$datum['idnumber'];
    // if idnumber already exists, then dont log it again
    if(!isset($convert_list[$idnumber])) $convert_list[$idnumber]=$index;
}

// create a NEW parent with the index of the entry with that idnumber
reset($data); // pointer to start
while(list($index,$datum)=each($data)) // loop through data
{
    $parent=$datum['parent'];
    if($parent==0)
    {
        // no parent
        $data[$index]['new_parent']=0;
    }
    else
    {
        // check if idnumber actually exists, otherwise say its not found
        if(isset($convert_list[$parent]))
        {
            $data[$index]['new_parent']=$convert_list[$parent];
        }
        else
        {
            $data[$index]['new_parent']='not found';
        }
    }
}

我希望这有帮助
