The historical browsing function uses the cookie function to record user information and store it locally. In this way, we only need to read the value stored in cookies. Let me introduce one to you. Example of implementing browsing history function based on thinkphp.

Just like a browser, it can record which pages have been visited, which can reduce time. Next, we implement the browsing history function.

1. On the product or news page where you need to record browsing data, record the information that the cookie needs to save. For example, in the following line of code, pass the page ID, product name, price, thumbnail, and URL to cookie_history.

cookie_history($id,$info['title'],$info['price'],$info['pic'],$thisurl);

2. Add the code in function.php

/**
  +----------------------------------------------------------
 * 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());
