getting mysql_insert_id() while using ON DUPLICATE KEY UPDATE with PHP

Question

I\'ve found a few answers for this using mySQL alone, but I was hoping someone could show me a way to get the ID of the last inserted or updated row of a mysql DB when using

This is my solution where you put the data into a single array and it's automatically duplicated/populated into the "INSERT INTO .. ON DUPLICATE UPDATE .. " query.

It's great for maintainability, and if you want you can make it a function / method too.

// save to db:

$qData = [
    "id" =>                mysql_real_escape_string($email_id),     
    "synd_id" =>           mysql_real_escape_string($synd_id),
    "campaign_id" =>       mysql_real_escape_string($campaign_id),
    "event_id" =>          mysql_real_escape_string($event_id),
    "user_id" =>           mysql_real_escape_string($user_id),
    "campaign_name" =>     mysql_real_escape_string($campaign_name), 
    "subject" =>           mysql_real_escape_string($subject),
    "from_name"=>          mysql_real_escape_string($from_name),
    "from_email"=>         mysql_real_escape_string($from),
    "content"=>            mysql_real_escape_string($html),
    "link_to_template" =>  mysql_real_escape_string($hash),
    "ext_campaign_id" =>   mysql_real_escape_string($ext_campaign_id),
    "ext_list_id"=>        mysql_real_escape_string($ext_list_id),
];


$q = "INSERT INTO email_campaigns (".
  // i.e create a string like `id`, `synd_id`, `campaign_id`..  with linebreaks for readability
  implode(", \n", array_map(function($k){ return "`$k`"; }, array_keys($qData)))
.")
VALUES (".
  // i.e '20', '532', '600' .. 
  implode(", \n", array_map(function($v){ return "'$v'"; }, array_values($qData)))
." )  ON DUPLICATE KEY UPDATE ".
  // i.e `synd_id`='532', `campaign_id`='600' ... 
  // id & link_to_template table keys are excluded based on the array below
  implode(", \n", array_filter(array_map(function($k, $v){ if(!in_array($k, ['id', 'link_to_template']) ) return "`$k`='$v'" ; }, array_keys($qData), array_values($qData))))  ;
