Convert strings to associative array - php

Question

I have five strings:
$array_key = "f_name, f_qty, f_price, f_cur_date";
$food_name = "Meal for 2, Four Seasons Pizza, Lunch Deal, Pepsi";
$food_qty = "1, 3, 5, 7";
$food_price = "10, 30, 50, 70";
$food_userId = "1, 2, 3, 4";
I need some array like this:
Array (
[0] => Array (
[f_name] => Meal for 2
[f_qty] => 1
[f_price] => 10
[f_cur_date] => 1
)
[1] => Array (
[f_name] => Four Seasons Pizza
[f_qty] => 3
[f_price] => 30
[f_cur_date] => 2
)
[2] => Array (
[f_name] => Lunch Deal
[f_qty] => 5
[f_price] => 50
[f_cur_date] => 3
)
[3] => Array (
[f_name] => Pepsi
[f_qty] => 7
[f_price] => 70
[f_cur_date] => 4
))
I convert strings to array with "explode":
$array_key_parts = explode(",",$array_key);
$food_name_parts = explode(",",$food_name);
$food_qty_parts = explode(",",$food_qty);
$food_price_parts = explode(",",$food_price);
$food_price_parts = explode(",",$food_price);
But don't know how to customize it further.
Basically, I'm getting this strings from query GROUP_CONCAT to use it in fullcalendar.js.

You can make an array using array_map function like below :
$food_name_parts = explode(",",$food_name);
$food_qty_parts = explode(",",$food_qty);
$food_price_parts = explode(",",$food_price);
$array_key_parts = explode(",",$array_key);
$myarray = array_map(function ($f_name, $f_qty, $f_price) {
return compact('f_name','f_qty','f_price');
}, $food_name_parts, $food_qty_parts, $food_price_parts);
echo "<pre>";
print_r($myarray);
