Remove key in multidimensional array - php

Question

I want to delete key [Price] but the function which I use for deletion doesn't work for this case
I have:
Array(
[Values] => 1
[Product] => Array(
[Details] => Array(
[ID] => 1
[Price] => Array(
)
)
)
)
My goal is:
Array(
[Values] => 1
[Product] => Array(
[Details] => Array(
[ID] => 1
)
)
)
I use this for removal:
function remove_key($array, $key)
{
foreach($array as $k => $v) {
if(is_array($v)) {
$array[$k] = remove_key($v, $key);
} elseif($k == $key) {
unset($array[$k]);
}
}
return $array;
}
$array = remove_key($array,'Price');
What is wrong here?

Answer 1

<?php
$array = Array(
'Values' => 1,
'Product' => Array(
'Details' => Array(
'id' => 1,
'Price' => Array(
)
)
)
);
unset($array['Product']['Details']['Price']);
echo "<pre>";
print_r($array);
echo "</pre>";
And the output is :
Array
(
[Values] => 1
[Product] => Array
(
[Details] => Array
(
[id] => 1
)
)
)

Answer 2

so if you want to fix your function you must add another condition into first if as so && $k != $key
because you are not getting into elseif and unset is not called
function remove_key($array, $key)
{
foreach($array as $k => $v) {
if(is_array($v) && $k != $key) {
$array[$k] = remove_key($v, $key);
} elseif($k == $key) {
unset($array[$k]);
}
}
return $array;
}
