来自多个foreach循环的新数组

Question

I am trying to create an array out of three arrays in the following manner:

    $file_data = array();

    foreach($file_ids as $key => $id){
       foreach($file_names as $name_key => $name){
          foreach($file_amounts as $file_key => $cost){
             $file_data[] = array("id" => $id, "filename" => $name, "amount" => $cost);
             break;
         }
         break;
      }

   }

It's creating the first row only. How can I get it to properly assign the values to the $file_data array?

Thanks.

UPDATE: As an example, I have the following for the three arrays

    $file_ids[0] = 2;
    $file_ids[1] = 4;

    $file_name[0] = name1;
    $file_name[1] = name2;

    $file_amount[0] = 10;
    $file_amount[1] = 9;

These arrays will always be of the same size.

What I would like to do is iterate over these arrays and end up with a final array of the form:

$final_array = (id, name, amount)

for all rows in other arrays.

Answer 1

These arrays will always be of the same size.

Just loop to the width of either array:

$final_array = array();
for($i = 0; $i < count($file_name); $i++)
{
    $final_array[] = array($file_ids[$i],$file_name[$i],$file_amount[$i]);
}
