I have a multidimensional array in Parent-Child format.
I want to add a new id in the array. The new id 'TTID' will be set in the order of Parent-Child. Meaning if ParentTTID is 1 then Child TTID should be 2, and its child should be 3.
So it's in order of Parent->Child->CHild. with unlimited levels of depth. Now the New Parent node id will start from last child's ID say 4 and its child will be 5 and so on
Array
(
[0] =Array
(
[id] =0
[value] =Total Income
[parent] =-1
[ttid] =1
[children] =Array
(
[0] =Array
(
[id] =2
[value] =Total Contributions
[parent] =0
[ttid] =0
[children] =Array
(
[0] =Array
(
[id] =5
[value] =Total Employers Contributions
[parent] =2
[ttid] =0
[children] =Array
(
[0] =Array
(
[id] =10
[value] =Employes unclassfied Contributions
[parent] =5
[ttid] =0
)
)
)
[1] =Array
(
[id] =1
[value] =Total Expenses
[parent] =-1
[ttid] =0
[children] =Array
(
[0] =Array
(
[id] =4
[value] =Total Benifit Payments
[parent] =1
[ttid] =0
[children] =Array
(
[0] =Array
(
[id] =9
[value] =Directly to Participant
[parent] =4
[ttid] =0
[children] =Array
(
[0] =Array
(
[id] =14
[value] =Some participant
[parent] =9
[ttid] =0
)
)
)
)
)
)
)
)
I tried to solve this using a method where I send 1 parent node Id at a time so that all its child will get marked. However, it doesn't seem to be working and it also gives me a warning: Cannot use a scalar value as an array in the line
function treetable_markRowChildren($elements,$parentId,$new_id)
{
$i = 1; $arr=array();
foreach ($elements as $element)
{
if ($element['parent'] == $parentId)
$element['ttid'] = $new_id+$i; // The Error is shown in this line
$i=$i+1;
$new_id=$element['ttid'];
if(isset($element['children']))
{
$parentId=$element['id'];
$arr2= treetable_markRowChildren($element,$parentId,$new_id);
}
else
break; //No CHildren
$arr=$element;
}
return $arr;
}
I just want the TTID to be set in this sequential format. How do I achieve this? Thanks in advance.
