Combining Three Arrays in foreach loop in PHP

Question

I know how to combine two arrays in foreach loop using array_combine() function of PHP

But I have three arrays and I want to loop through all of three arrays at a time.

$get_id=$data->get_id;
$get_product=$data->get_product;
$get_comment=$data->get_comment;

foreach (array_combine($get_id, $get_product) as $id => $product) {
    echo "$id - $product<br/>";

}

I want to iterate $get_comment array too in this loop.

Thanks

If these arrays are numerically indexed, you could use a for loop. — Amal

These arrays are having random values from ajax JSON request — explorecode

Not concerned about the values for the time being but the keys assigned to these values... What about the keys... Are they assigned by you or system generated (or as pointed by @AmalMurali) / numerically indexed. — Vagabond

@explorecode: I'm talking about their keys, not values. Can you show the print_r() outputs of the array? — Amal

I think this might be what you are looking for:

$get_id=$data->get_id;
$get_product=$data->get_product;
$get_comment=$data->get_comment;

foreach($get_id as $i => $id){
    $product = $get_product[$i];
    $comment = $get_comment[$i];
    echo "$id , $product, $comment<br/>";
}

This solution assumes the $get_id, $get_product, and $get_comment arrays are all indexed the same way.

Combine the arrays before the foreach loop

    $comment_array = array_combine($get_id, $get_comment);
    $product_array = array_combine($get_id, $get_product);
    foreach ($product_array as $id => $product) {
      $comment = $comment_array[$id];
    }

Will it work because $get_id contains alphanumeric characters?

Shouldn't be a problem, all arrays in PHP are associative.
