Combining Three Arrays in foreach loop in PHP

问题

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

回答1:

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];
    }
