array_values recursive php - php

Question

Let's say I have an array like this:
Array
(
[id] => 45
[name] => john
[children] => Array
(
[45] => Array
(
[id] => 45
[name] => steph
[children] => Array
(
[56] => Array
(
[id] => 56
[name] => maria
[children] => Array
(
[60] => Array
(
[id] => 60
[name] => thomas
)
[61] => Array
(
[id] => 61
[name] => michelle
)
)
)
[57] => Array
(
[id] => 57
[name] => luis
)
)
)
)
)
What I'm trying to do is to reset the keys of the array with keys children to 0, 1, 2, 3, and so on, instead of 45, 56, or 57.
I tried something like:
function array_values_recursive($arr)
{
foreach ($arr as $key => $value)
{
if(is_array($value))
{
$arr[$key] = array_values($value);
$this->array_values_recursive($value);
}
}
return $arr;
}
But that reset only the key of the first children array (the one with key 45)

Answer 1

function array_values_recursive($arr)
{
$arr2=[];
foreach ($arr as $key => $value)
{
if(is_array($value))
{
$arr2[] = array_values_recursive($value);
}else{
$arr2[] = $value;
}
}
return $arr2;
}
this function that implement array_values_recursive from array like:
array(
'key1'=> 'value1',
'key2'=> array (
'key2-1'=>'value-2-1',
'key2-2'=>'value-2-2'
)
);
to array like:
array(
0 => 'value1',
1 => array (
0 =>'value-2-1',
1 =>'value-2-2'
)
);

Answer 2

You use a recursive approach but you do not assign the return value of the function call $this->array_values_recursive($value); anywhere. The first level works, as you modify $arr in the loop. Any further level does not work anymore for mentioned reasons.
If you want to keep your function, change it as follows (untested):
function array_values_recursive($arr)
{
foreach ($arr as $key => $value)
{
if (is_array($value))
{
$arr[$key] = $this->array_values_recursive($value);
}
}
if (isset($arr['children']))
{
$arr['children'] = array_values($arr['children']);
}
return $arr;
}

Answer 3

This should do it:
function array_values_recursive($arr, $key)
{
$arr2 = ($key == 'children') ? array_values($arr) : $arr;
foreach ($arr2 as $key => &$value)
{
if(is_array($value))
{
$value = array_values_recursive($value, $key);
}
}
return $arr2;
}

Answer 4

Try this ,
function updateData($updateAry,$result = array()){
foreach($updateAry as $key => $values){
if(is_array($values) && count($values) > 0){
$result[$key] = $this->_updateData($values,$values);
}else{
$result[$key] = 'here you can update values';
}
}
return $result;
}

You can used php fnc walk_array_recursive
