php - Multidimensional arrays to insert for one row

Question

I have three arrays that look like this:

ingredientQTY is the first input box in each row, measurements is the select/dropdown in each row, and ingredientsNAME is the last input box in each row. As you can see, there can be infinite numbers of ingredientQTY's, ingredientNAME's, and measurements.

When I send them to my php script, the data is in arrays like:

IngredientQTY
(
  [0] => 5 //The first row 
  [1] => 5 //The next rows value
)   
Measurements
(
  [0] => Bunch  //The first row
  [1] => Bunch  //The next rows value
)   
IngredientName
(
  [0] => 5   //The first row
  [1] => 5   //The next rows value
)

I'm trying to upload them to a table called ingredients that has 3 columns: ingredientNAME, ingredientQTY, and measurements.

In my php script, I'm combining them into a multidimensional array, which is assigned to $ingredientsROW:

foreach($_POST as $key => $value) {
      $value = $this->input->post($key);
      $ingredientQTY = $this->input->post('ingredientQTY');
      $measurements = $this->input->post('measurements');
      $ingredientNAME = $this->input->post('ingredientNAME');
      $ingredientsROW[] = array($ingredientQTY, $measurements, $ingredientNAME);
      break;
}

My question is: How can I get group all the first row of form elements (which means the first ingredientQTY, the first measurements dropdown and the first ingredientNAME and insert them into a row?

The only way I could think of is to have one insert where I insert ingredientQTY, then look up the id of the row I just inserted and use two mysql updates to enter for the same row, but I'm pretty sure there is more efficient ways of going about this.

Would something like this work?

foreach($_POST['IngredientQTY'] as $index=>$qty)
    mysql_query("insert into ingredients ".
                 "set IngredientQTY='".addslashes($qty)."'".
                 ", measurements ='".addslashes($_POST['measurements'][$index])."'".
                 ", ingredientNAME ='".addslashes($_POST['ingredientNAME'][$index])."');

Iterate through the data and create an array like this:

for ($i = 0, $count = count($ingredientQTY); $i < $count; $i++) {
   $rows[] = array(
       'QTY'         => $ingredientQTY[$i],
       'measurement' =>  $measurements[$i],
       'name'        => $ingredientNAME[$i]
   );
}

With this array you can create the insert quite easily and insert whole rows.
