2.function.php 里面添加代码
/** +---------------------------------------------------------- * 浏览记录按照时间排序 +---------------------------------------------------------- */ function my_sort($a, $b){ $a = substr($a,1); $b = substr($b,1); if ($a == $b) return 0; return ($a > $b) ? -1 : 1; } /** +---------------------------------------------------------- * 网页浏览记录生成 +---------------------------------------------------------- */ function cookie_history($id,$title,$price,$img,$url){ $dealinfo['title'] = $title; $dealinfo['price'] = $price; $dealinfo['img'] = $img; $dealinfo['url'] = $url; $time = 't'.NOW_TIME; $cookie_history = array($time => json_encode($dealinfo)); //设置cookie if (!cookie('history')){//cookie空,初始一个 cookie('history',$cookie_history); }else{ $new_history = array_merge(cookie('history'),$cookie_history);//添加新浏览数据 uksort($new_history, "my_sort");//按照浏览时间排序 $history = array_unique($new_history); if (count($history) > 4){ $history = array_slice($history,0,4); } cookie('history',$history); } } /** +---------------------------------------------------------- * 网页浏览记录读取 +---------------------------------------------------------- */ function cookie_history_read(){ $arr = cookie('history'); foreach ((array)$arr as $k => $v){ $list[$k] = json_decode($v,true); } return $list; }
$this->assign('history',cookie_history_read());
希望本文所述对大家的PHP程序设计有所帮助。
