How to store a PHP object in memory (or in memory) between AJAX calls

Question

I have the following class definition:

class DatasegmentationController
{
    public function indexAction()
    {
        $options['permissions'] = array(
            'canDelete'     => false,
            'canEdit'       => false
        );

        if ($this->getRequest()->isXmlHttpRequest()) {
            $table = $this->getRequest()->getParam('table');

            if ($table !== '' && $table !== null) {
                $utilStr = new UtilString();

                // This is a patch because class and tables names does not match
                // so far it only happens with company and this is only for
                // instantiate the proper class dynamically
                $param_table = $table;
                $table       = $table === 'companies' ? 'company' : $table;
                $classObj    = strpos($table, '_') !== false ? $utilStr->stringToCamelCase($table, '_') : $utilStr->stringToCamelCase($table);
                $className   = new $classObj();

                $module_map = $field_map[$param_table];

                /** @var  $module_map array */
                $fields = [];
                foreach ($module_map as $key => $value) {
                    $fields[] = [
                        'id'   => $key,
                        'text' => $key
                    ];
                }

                $conditions      = json_decode($this->_request->getParam('conditions'), true);
                $dynDataGridName = "DataSegmentation{$this->classObj}Grid";
                $dynMethodName   = "get{$this->classObj}GridModel";

                $gridObj = new $dynDataGridName(
                    $this->className->$dynMethodName($conditions),
                    $this->view->users_id,
                    "{$table}_list",
                    "{$table}.{$table}_id",
                    '/datasegmentation/index',
                    'editor',
                    $options
                );

                return $this->_helper->json([
                    'fields' => $fields,
                    'grid'   => $gridObj->getGridJs()
                ]);
            }

            if (isset($classObj, $className, $gridObj)) {
                $page  = $this->_request->getParam('page', 1);
                $limit = $this->_request->getParam('rows', 20);
                $col   = $this->_request->getParam('sidx', 1);
                $order = $this->_request->getParam('sord', 0);
                $search  = $this->_request->getParam('val', null);

                echo $gridObj->getData($page, $limit, $col, $order, $search);
            }
        }
    }
}

What the following code does:

• URL http://localhost/datasegmentationis called
• View displays a select ( modules) element with parameters
• When changing, select#modulesI sent this value as part of the URL, so the next AJAX call will look like this: http://localhost/datasegmentation?table=companies(for example)
• The function indexAction()then performs what is on the condition when $tableit is not empty or not null.
• Among all these things, he is trying to generate everything dynamically, as you can see in the code.
• ($gridObj), AJAX indexAction(),
• , , AJAX, indexAction(), , , , .
