我有一个数组，我添加到这篇文章的末尾。我需要将数组的'parent'值设置为父数组索引号.Arrays与父数组相关的父值idnumber value。
例如;
[131] => Array
(
[idnumber] => 171
[name] => 9f146bfd1b1aa02612b95a0ae7b52f13
[parent] => 21
)
Parrent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很难; idnumbers必须是唯一的，但前22个数组（父值为0）idnumbers可以找到其余的数组idnumber（不多）。这使得我很难解决这个问题。我尝试了不同的方法，但每种方式效率都不高我想要的。

答案 0 :(得分：0)
这是一个解决方案，假设如果idnumber出现多次，那么父母将仅引用第一次出现。
// 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';
}
}
}
我希望这会有所帮助
