Using ZeroMQ (PHP-ZMQ) for loop operations - php

Question

I'm trying to use heavy resource content loop operation with ZeroMQ (PHP-ZMQ) via tcp protocol.
I've got below code so far:
class SJB_Miscellaneous_SendNotifications extends SJB_Function
{
public function execute()
{
try{
set_time_limit(0);
$i18n = SJB_I18N::getInstance();
$lang = $i18n->getLanguageData($i18n->getCurrentLanguage());
$current_date = strftime($lang['date_format'], time());
// Send Search Notifications
$saved_searches = SJB_SavedSearches::getAutoNotifySavedSearches();
// echo "<pre>"; print_r($saved_searches); echo "</pre>"; exit;
$listing = new SJB_Listing();
$notified_saved_searches_sid = array();
$notificationsLimit = (int) SJB_Settings::getSettingByName('num_of_listings_sent_in_email_alerts');
/* ZeroMQ implementation */
$queue = new ZMQSocket(new ZMQContext(), ZMQ::SOCKET_REQ, "MySock1");
$queue->connect("tcp://127.0.0.1:5555");
/* Assign socket 1 to the queue, send and receive */
$time = time();
$queue->send(json_encode($saved_searches));
// echo $queue->recv();
// exit;
$count = 1;
// array_shift($saved_searches);
$server = new ZMQSocket(new ZMQContext(), ZMQ::SOCKET_REP);
$server->bind("tcp://127.0.0.1:5555");
$msg = $server->recv();
$saved_searches = json_decode($msg, true);
// echo "<pre>"; var_dump($saved_searches); echo "</pre>";
// exit;
foreach ($saved_searches as $saved_search) {
$searcher = new SJB_ListingSearcher();
$listing->addActivationDateProperty();
$search_data = unserialize($saved_search['data']);
$search_data['active']['equal'] = 1;
$datearr = explode('-', $saved_search['last_send']);
$saved_search['last_send'] = strftime($lang['date_format'], mktime(0, 0, 0, $datearr[1], $datearr[2], $datearr[0]));
$search_data['activation_date']['not_less'] = $saved_search['last_send'];
$search_data['activation_date']['not_more'] = $current_date;
$listing_type_sid = 0;
if ($search_data['listing_type']['equal']) {
$listing_type_id = $search_data['listing_type']['equal'];
$listing_type_sid = SJB_ListingTypeManager::getListingTypeSIDByID($listing_type_id);
if (SJB_ListingTypeManager::getWaitApproveSettingByListingType($listing_type_sid))
$search_data['status']['equal'] = 'approved';
}
// echo "<pre>"; echo $saved_search['user_sid']; print_r($listing_type_id); echo "</pre>"; exit;
$id_alias_info = $listing->addIDProperty();
$username_alias_info = $listing->addUsernameProperty();
$listing_type_id_info = $listing->addListingTypeIDProperty();
$aliases = new SJB_PropertyAliases();
$aliases->addAlias($id_alias_info);
$aliases->addAlias($username_alias_info);
$aliases->addAlias($listing_type_id_info);
$search_data['access_type'] = array(
'accessible' => $saved_search['user_sid'],
);
$criteria = SJB_SearchFormBuilder::extractCriteriaFromRequestData($search_data, $listing);
$searcher->found_object_sids = array();
$searcher->setLimit($notificationsLimit);
$sorting_fields = array('CityRegion' => 'ASC');
$found_listings_ids = $searcher->getObjectsSIDsByCriteria($criteria, $aliases, $sorting_fields);
// echo "<pre>"; var_dump($found_listings_ids); echo "</pre>";
if (count($found_listings_ids)) {
$saved_search['activation_date'] = $saved_search['last_send'];
if (SJB_Notifications::sendUserNewListingsFoundLetter($found_listings_ids, $saved_search['user_sid'], $saved_search, $listing_type_sid)) {
SJB_Statistics::addStatistics('sentAlert', $listing_type_sid, $saved_search['sid']);
SJB_DB::query('UPDATE `saved_searches` SET `last_send` = CURDATE() WHERE `sid` = ?n', $saved_search['sid']);
}
$notified_saved_searches_sid[] = $saved_search['sid'];
}
echo nl2br($count."\n");
$count++;
}
// To be entered from task_scheduler.php
$expired_contracts_id = null; $expired_listings_id = null;
$template_processor = SJB_System::getTemplateProcessor();
$template_processor->assign('expired_listings_id', null);
$template_processor->assign('deactivated_listings_id', null);
$template_processor->assign('expired_contracts_id', null);
$template_processor->assign('notified_saved_searches_id', $notified_saved_searches_sid);
$scheduler_log = $template_processor->fetch('task_scheduler_log.tpl');
if ($log_file = #fopen('task_scheduler.log', 'a+')) {
fwrite($log_file, $scheduler_log);
fclose($log_file);
}
SJB_DB::query('INSERT INTO `task_scheduler_log`
(`last_executed_date`, `notifieds_sent`, `expired_listings`, `expired_contracts`, `log_text`)
VALUES ( NOW(), ?n, ?n, ?n, ?s)',
count($notified_saved_searches_sid), count($expired_listings_id), count($expired_contracts_id), $scheduler_log);
} catch(Exception $e){
echo $e->getMessage();
}
}
} // END class SJB_Miscellaneous_SendNotifications extends SJB_Function
Is there a good way to utilise ZeroMQ for this type of operation where I want to free loop operations especially when it reaches $saved_searches foreach loop?
