How to convert array to list without .= in PHP?

[YaKu]

I have the following array outputs.\[code\]Array( [day] => 17 [eventContent] => event 1 of 17th [eventTitle] => 17th event 1)Array( [day] => 19 [eventContent] => event 1 of 19th [eventTitle] => 19th event 1)Array( [day] => 05 [eventContent] => event 1 of 5th [eventTitle] => 5th event 1)Array( [day] => 17 [eventContent] => event 2 of 17th [eventTitle] => 17th event 2)Array( [day] => 19 [eventContent] => event 2 of 19th [eventTitle] => 19th event 2)Array( [day] => 19 [eventContent] => event 3 of 19th [eventTitle] => 19th event 3)......\[/code\]Now I want to make it like the followings.For example for 19th\[code\]<li><span class="title">19th event 1</span><span class="desc">event 1 of 19th</span></li><li><span class="title">19th event 2</span><span class="desc">event 2 of 19th</span></li><li> <span class="title">19th event 3</span><span class="desc">event 3 of 19th</span></li>\[/code\]I tried the following. It works fine in PHP but not in Codeigniter. So I am hoping someone can tell me another way to do with out .=Thanks in advance.\[code\]$events[intval($row_event->day)] .= '<li><span class="title">'.stripslashes($row_event->eventTitle).'</span><span class="desc">'.stripslashes($row_event->eventContent).'</span></li>';\[/code\]And the following is the details of the model.\[code\]$events = array();//query the database for events between the first date of the month and the last of date of month// $result = mysql_query("SELECT DATE_FORMAT(eventDate,'%d') AS day,eventContent,eventTitle FROM eventcal WHERE eventDate BETWEEN '$current_year/$current_month/01' AND '$current_year/$current_month/$total_days_of_current_month'");$query = $this->db->query("SELECT DATE_FORMAT(eventDate,'%d') AS day,eventContent,eventTitle FROM eventcal WHERE eventDate BETWEEN '$current_year/$current_month/01' AND '$current_year/$current_month/$total_days_of_current_month'");foreach ($query->result_array() as $row_event){$events[intval($row_event['day'])] .= '<li><span class="title">'.stripslashes($row_event['eventTitle']).'</span><span class="desc">'.stripslashes($row_event['eventContent']).'</span></li>';......\[/code\]--UPDATE--ControllerCode hereViewCode hereErrors\[code\]A PHP Error was encounteredSeverity: NoticeMessage: Undefined offset: 17Filename: models/mcalendar_one.phpLine Number: 38Array( [day] => 17 [eventContent] => event 1 of 17th [eventTitle] => 17th event 1)A PHP Error was encounteredSeverity: NoticeMessage: Undefined offset: 19Filename: models/mcalendar_one.phpLine Number: 38Array( [day] => 19 [eventContent] => event 1 of 19th [eventTitle] => 19th event 1)......\[/code\]
