Insert Multiple array value in same row php - php

Question

How can I insert Multiple array value in mysql table at same time?
I can handle single value Insertion.
Eg:
$product = json_decode($_POST['product']); // (1,2)
$sub_product = json_decode($_POST['sub_product']); // (3,4)
$plan = json_decode($_POST['plan']);// (5,6)
$months = json_decode($_POST['months']); // (7,8)
I want to insert value with same index in mysql
Something like:
+----+---------+-------------+------+--------+
| id | product | sub_product | plan | months |
+----+---------+-------------+------+--------+
| 1 | 1 | 3 | 5 | 7 |
+----+---------+-------------+------+--------+
| 2 | 2 | 4 | 6 | 8 |
+----+---------+-------------+------+--------+
I've tried Insertion for single column and it works perfectly.
for ($i = 0; $i < count($product); $i++) {
$product = mysql_real_escape_string($product[$i]);
mysql_query("INSERT INTO i_product(product) VALUES('$product')");
}

you can execute multiple INSERT operations in the following format,
INSERT INTO tbl_name
(a,b,c)
VALUES
(d,e,f),
(g,h,i),
(j,k,l);
Here's the reference:
INSERT Syntax
Since you're getting the data as an array, your INSERT operation should be like this:
// your code
mysql_query("INSERT INTO i_product(product, sub_product, plan, months)
VALUES
('" . mysql_real_escape_string($product[0]) . "', '" .
mysql_real_escape_string($sub_product[0]) . "', '" .
mysql_real_escape_string($plan[0]) . "', '" .
mysql_real_escape_string($months[0]) . "'),
('" . mysql_real_escape_string($product[1]) . "', '" .
mysql_real_escape_string($sub_product[1]) . "', '" .
mysql_real_escape_string($plan[1]) . "', '" .
mysql_real_escape_string($months[1]) . "')");
Sidenote: Please don't use mysql_ database extensions, they are deprecated as of PHP 5.5 and are removed altogether in PHP 7. Use mysqli or PDO instead.
