jquery - PHP, Singleton and $.ajax -

it seems $.ajax (jquery) doesn't work php singleton.

i have simple class defined this:

class mysingleton {     protected static $instance = null;     private $array;     protected function __construct()     {        ...        $this->array = array();        //get database,         $this->array[] = object database;        $this->array[] = object database;        ...     }     protected function __clone()     {     }      public static function getinstance()     {         if (!isset(static::$instance)) {             static::$instance = new static;         }         return static::$instance;     }      public function somefunction() {          $this->array[0]->somefield = "set without saving database";          ...     } } 

i have helper.php file singleton object something. ie:

<?php require "mysingleton.php"; $singleton = mysingleton::getinstance(); $singleton->somefunction(); $singleton->someotherfunction(); ?> 

in index.php, tried use $.ajax me:

$.each(data, function(key, value) {              $.ajax({                 url: 'helper.php',                 type: 'post',                 data: somedata,                 datatype: 'json'             }).always(function(result) {                  ...              });  });//each 

as can see in jquery code, have called $.ajax few times.

i traced mysingleton, , instead of returning same instance, created few times (depending on $.each loop size).

i have read article: http://www.daniweb.com/web-development/php/threads/393405/php-singletone-pattern-in-php-files-where-ajaxs-requests-are-sent

and happens because of singleton pattern work during same request. in case have few ajax requests (again, based on $.each loop) , that's why never worked.

the reason using singleton object because don't want make multiple database connections, mysingleton have array (which used store objects) , in mysingleton class use array temporary store information without saving database)

so there anyway solve problem? want use $.ajax , php singleton.

the way save data between requests storing somewhere. means either session or file or in database.

i don't think loading data @ once slower loading 1 record, because 90% if loading time creating request, creating database connection etc. how try load data @ once , if slow can add cache or else on top of it, pretty sure fast enought.
