ช่วยดู array นี้ให้หน่อยครับ อยากรู้ว่าเป็น Associative Array หรือเปล่าครับ

$options = array (

  array(  "name" => "Welcome Message",
      "type" => "title"),
      
  array(  "type" => "open"),
  
  array(  "name" => "Title",
      "desc" => "Enter a title to display for your welcome message.",
      "id" => $shortname."_welcome_title",
      "std" => "",
      "type" => "text"),
      
  array(  "name" => "Message",
      "desc" => "Text to display as welcome message.",
            "id" => $shortname."_welcome_message",
            "type" => "textarea"),
  
  array(  "name" => "Disable Welcome Message?",
      "desc" => "Check this box if you would like to DISABLE the welcome message.",
            "id" => $shortname."_welcome_disable",
            "type" => "checkbox",
            "std" => "false"),
  
  array(  "type" => "close")
  
);
