how to return multidimensional array in codeigniter - php

Question

guys i have multidimensional array which i got it from var_dump of $menu_order with this following array :
array(5) {
[0]=>
array(1) {
[0]=>
array(1) {
["variant_name"]=>
string(5) "Spicy"
}
}
[1]=>
array(2) {
[0]=>
array(1) {
["variant_name"]=>
string(5) "Spicy"
}
[1]=>
array(1) {
["variant_name"]=>
string(5) "small"
}
}
[2]=>
array(2) {
[0]=>
array(1) {
["variant_name"]=>
string(5) "Salty"
}
[1]=>
array(1) {
["variant_name"]=>
string(6) "medium"
}
}
[3]=>
array(2) {
[0]=>
array(1) {
["variant_name"]=>
string(12) "Mix of Herbs"
}
[1]=>
array(1) {
["variant_name"]=>
string(5) "large"
}
}
[4]=>
array(0) {
}
}
from that array, i need to get the variant_name become variant_menu_id with this following code :
foreach ($menu_order as $item) {
if (isset($item[0]["variant_name"])) {
foreach($item as $value) {
$variant_id[] = $this->Main_home_m->m_get_choice_id($value["variant_name"]);
}
} else {
$variant_id[] = array();
}
}
the model of m_get_choice_id have this following code :
Function m_get_choice_id($variant_name){
$this->db->select("variant_menu_id");
$this->db->from("uhd_variant_menu");
$this->db->where("variant_name",$variant_name);
$query = $this->db->get();
return $query->row_array();
}
the variant_id will be return to this multidimensional array :
array(8) {
[0]=>
array(1) {
["variant_menu_id"]=>
string(1) "3"
}
[1]=>
array(1) {
["variant_menu_id"]=>
string(1) "3"
}
[2]=>
array(1) {
["variant_menu_id"]=>
string(1) "6"
}
[3]=>
array(1) {
["variant_menu_id"]=>
string(1) "4"
}
[4]=>
array(1) {
["variant_menu_id"]=>
string(1) "7"
}
[5]=>
array(1) {
["variant_menu_id"]=>
string(1) "5"
}
[6]=>
array(1) {
["variant_menu_id"]=>
string(1) "8"
}
[7]=>
array(0) {
}
}
but i want the result variant_id become this multidimensional array :
array(5) {
[0]=>
array(1) {
[0]=>
string(1) "3"
}
[1]=>
array(2) {
[0]=>
string(1) "3"
[1]=>
string(1) "6"
}
[2]=>
array(2) {
[0]=>
string(1) "4"
[1]=>
string(1) "7"
}
[3]=>
array(2) {
[0]=>
string(1) "5"
[1]=>
string(1) "8"
}
[4]=>
array(0) {
}
}
guys can you help me how to get the multidimensional array?
thank you (:

Alternatively, you can create a temporary container holding the ids with an array. After getting them all as an array, push that whole batch inside a parent container:
$result = array();
foreach ($menu_order as $item) {
$temp = array(); // initialize temporary storage
if (isset($item[0]["variant_name"])) {
foreach($item as $value) {
$variant = $this->Main_home_m->m_get_choice_id($value["variant_name"]);
$temp[] = $variant['variant_menu_id']; // push single id into temporary storage
}
}
$result[] = $temp; // push ending batch
}
