How do I insert textarea values one at a time into database?

Question

I have a a simple form:
Select List - populated by a recordset that gets a list of technicians.   In this format:   Label - >  Tech name   Value - > Tech ID
Textarea - To paste zip codes into that the tech services.    In this format:   12345,12346,12347,etc..
When I want to submit the form, I want it to take all of those zip codes and insert them into the database as a single record each with the tech's id from the select list. 
The code I have is thus:
$zipcodes = explode(",", $_POST['textarea']);
$countZips = (count($zipcodes));
if ((isset($_POST["MM_insert"])) && ($_POST["MM_insert"] == "form1")) {
foreach($zipcodes as $key=>$value)
while ($countZips >= 1) {
$editFormAction = $_SERVER['PHP_SELF'];
if (isset($_SERVER['QUERY_STRING'])) {
  $editFormAction .= "?" . htmlentities($_SERVER['QUERY_STRING']);
  $insertSQL = sprintf("INSERT INTO zip_zip (zip_code, tech_id) VALUES (%s, %s)",
                       GetSQLValueString($value, "int"),
                       GetSQLValueString($_POST['select'], "int"));
  mysql_select_db($database_localhost, $localhost);
  $Result1 = mysql_query($insertSQL, $localhost) or die(mysql_error());
          $countZips--;
//Done value exists
//Now moving to next page when done
          $insertGoTo = "index.php";
  if (isset($_SERVER['QUERY_STRING'])) {
    $insertGoTo .= (strpos($insertGoTo, '?')) ? "&" : "?";
    $insertGoTo .= $_SERVER['QUERY_STRING'];
  header(sprintf("Location: %s", $insertGoTo));
//END
The issue is - let's say I paste 105 zip codes into the text area.   It will insert the FIRST zip code 105 times into the database instead of inserting the 105 zip codes individually.
Any idea what I'm doing wrong here?
Thanks!

Ok, so all of that mysql stuff just needs to be ran once until the connection is closed.  I didn't know that.  That probably makes it run better too.
Ok, so here is what that code looks like now.  There are a few additions because it turns out I also have to check to make sure the zip code is in a state that the tech is licensed in.  : (  I have a question about how to do that because it is different.  Do I need to post a new question or is better to ask here since my stuff is usually in left field?
Any way here is my code now.  I think it is much better, right?
//Start
//This is my recordset to get the last tech added
mysql_select_db($database_localhost, $localhost);
$query_getTechs = "SELECT * FROM zip_tech ORDER BY tech_id DESC";
$getTechs = mysql_query($query_getTechs, $localhost) or die(mysql_error());
$row_getTechs = mysql_fetch_assoc($getTechs);
$totalRows_getTechs = mysql_num_rows($getTechs);
//This is where I'm getting all zip codes that are serviceable by stupid regulations
mysql_select_db($database_localhost, $localhost);
$query_Recordset1 = "SELECT zip_code, state_prefix FROM zip_code";
$Recordset1 = mysql_query($query_Recordset1, $localhost) or die(mysql_error());
$row_Recordset1 = mysql_fetch_assoc($Recordset1);
$totalRows_Recordset1 = mysql_num_rows($Recordset1);
//ARRAYS
$results = array();
$states = array();
do {
  $results[] = $row_Recordset1['zip_code'];
  $states[] = $row_Recordset1['state_prefix'];
} while ($row_Recordset1 = mysql_fetch_assoc($Recordset1));
//Check if form is filled out
if ((isset($_POST["MM_insert"])) && ($_POST["MM_insert"] == "form1")) {
//If so, explode textarea values into an array or something
$zipcodes = explode(",", $_POST['textarea']);
//MySQL Stuff
mysql_select_db($database_localhost, $localhost);
$editFormAction = $_SERVER['PHP_SELF'];
if (isset($_SERVER['QUERY_STRING'])) {
$editFormAction .= "?" . htmlentities($_SERVER['QUERY_STRING']);
//my loop to go through each zip code one by one
foreach($zipcodes as $value)
//Let's see if the value from the textarea is in our $results array from above
if (in_array($value, $results)){
//If it is in the array - then insert it into the database with the tech id
  $insertSQL = sprintf("INSERT INTO zip_zip (zip_code, tech_id) VALUES (%s, %s)",
                       GetSQLValueString($value, "int"),
                       GetSQLValueString($_POST['tech_id'], "int"));
  $Result1 = mysql_query($insertSQL, $localhost) or die(mysql_error());
//Done value exists
//Now moving to next page when done
          $insertGoTo = "index.php";
  if (isset($_SERVER['QUERY_STRING'])) {
    $insertGoTo .= (strpos($insertGoTo, '?')) ? "&" : "?";
    $insertGoTo .= $_SERVER['QUERY_STRING'];
  header(sprintf("Location: %s", $insertGoTo));
//END
