PHP Unset parent if not found in an array - php

Question

I'm having an issue unsetting my parent if I do not find my needle in my child, for some reason I just cannot get this to work no matter how many different ways I try it, could someone possibly point me in the right direction? This is being thrown at a multidimensional array with a floor depth of about 4. Here's the code and an example of what a slice of the array might look like. In this case only Array[3] should remain, Array's [1-2] should be removed.
array (
1 =>
array (
197015 =>
array (
345415 =>
array (
'options' =>
array (
'Name on Credential' => '',
'Ordination Month' => '',
'Ordination Day' => '',
'Ordination Year' => '',
'Badge Choice?' => '',
),
'comments' =>
array (
213354 => '',
),
'products_name' => '',
'products_quantity' => '',
'delivery_country' => '',
'customers_name' => '',
'delivery_name' => '',
'delivery_street_address' => '',
'delivery_city' => '',
'delivery_postcode' => '',
'delivery_state' => '',
'customers_telephone' => '',
),
),
),
2 =>
array (
197014 =>
array (
345414 =>
array (
'options' =>
array (
'Name on Credential' => '',
'Ordination Month' => '',
'Ordination Day' => '',
'Ordination Year' => '',
'Badge Choice?' => '',
),
'comments' =>
array (
213353 => '',
),
'products_name' => '',
'products_quantity' => '',
'delivery_country' => '',
'customers_name' => '',
'delivery_name' => '',
'delivery_street_address' => '',
'delivery_city' => '',
'delivery_postcode' => '',
'delivery_state' => '',
'customers_telephone' => '',
),
),
),
3 =>
array (
197013 =>
array (
345412 =>
array (
'options' =>
array (
'Name on Credential' => '',
'Ordination Month' => '',
'Ordination Day' => '',
'Ordination Year' => '',
),
'comments' =>
array (
213352 => '',
),
'products_name' => 'Jedi',
'products_quantity' => '1',
'delivery_country' => '',
'customers_name' => '',
'delivery_name' => '',
'delivery_street_address' => '',
'delivery_city' => '',
'delivery_postcode' => '',
'delivery_state' => '',
'customers_telephone' => '',
),
345413 =>
array (
'options' =>
array (
'' => '',
),
'comments' =>
array (
213352 => '',
),
'products_name' => '',
'products_quantity' => '',
'delivery_country' => '',
'customers_name' => '',
'delivery_name' => '',
'delivery_street_address' => '',
'delivery_city' => '',
'delivery_postcode' => '',
'delivery_state' => '',
'customers_telephone' => '',
),
),
),
Here's a sample of the last code I tried using without success, if you replace unset($k); with return false; it will return which secondary array the needle appears in.
// array_search with recursive searching, optional partial matches and optional search by key
function array_find_r($needle, &$haystack, $partial_matches = false, $search_keys = false) {
if(!is_array($haystack)) return false;
foreach($haystack as $key=>&$value) {
$what = ($search_keys) ? $key : $value;
if($needle===$what) return $key;
else if($partial_matches && #strpos($what, $needle)!==false) return $key;
else if(is_array($value) && array_find_r($needle, $value, $partial_matches, $search_keys)!==false) return $key;
}
unset($k);
}
$tty = array();
foreach($datas as &$k) {
$tty[] = array_find_r('Jedi', &$k, true, false);
}
$tty=array_filter($tty); rsort($tty);
echo '<pre>'; var_export($datas); echo '</pre>';

Answer 1

Why not push the data you do need into a new array and unset the whole old array?
