can we use foreach() for two different arrays at once?

Question

I am facing problem when I am trying to insert values from array to mysql database.

foreach ( $_POST['product_id'] as $key=>$value AND $_POST['discount'] as $key1=>$discount) { }

check the above given code where I am going wrong?

This is not valid syntax. To directly answer the question in te title, NO you cant do that — Steve, Jun 03 '14 at 11:59
You can't do it like that. Try [merging](http://pl1.php.net/array_merge) your array and iterate over merged array — Bartek, Jun 03 '14 at 11:59
That won't work. It's not logical, because you are not guaranteed to have same amount of products and discounts. Can you specify more precisely, what are you trying to achiev? — Serge Kuharev, Jun 03 '14 at 12:00
i am getting variable $_POST['product_id'],$_POST['discount'] by post method and i want to insert this two array values in my mysql database. — Anurag Garg, Jun 03 '14 at 12:01

You can use a regular for loop as long as the indexes match:

$count = count($_POST['product_id']);
for($i = 0; $i < $count; $i++) {
    echo $_POST['product_id'][$i];
    echo $_POST['discount'][$i];
}

use array_map this will loop through all keys in all arrays provided simultaneously.

array_map(function(){
  $args = func_get_args();
  foreach($args as $k => $v) {
    echo $v;
  }
}, $arr1, $arr2 ...);
