PHP Cookei’s code for recording user history browsing information, phpcookei

[Basics]

Common methods for cookies:

$_COOKIE['RecordLuHuiDUDU'] gets Cookie
setcookie('RecordLuHuiDUDU',",time()-3600*24*30); setcookie(field name, data, expiration time); Set Cookie

【Attention】

Resetting cookies requires invalidating previous cookies. The same method is used to delete cookies:
setcookie(‘RecordLuHuiDUDU’,”,time()-3600*24*30);

【Code Example】

/**
   * 将用品id存入Cookie中
   *
   * @param $id
   * @return bool
   */
  public function setCookieRecord($id){
    $data = null;
    if(!isset($_COOKIE['RecordLuHuiDUDU'])){
      if(!empty($id)) {
        $data[0] = array(
          'id' = $id,
          'time' = date('Y-m-d H:i:s', time())
        );
      }else{
        return false;
      }
    }else{
      if(!empty($id)) {
        $data = $_COOKIE['RecordLuHuiDUDU'];
        setcookie('RecordLuHuiDUDU','',time()-3600*24*30);
        $data = json_decode($data, true);
        $num = count($data);
        //判断是否重复
        $judge = false;
        foreach($data as $index => $value){
          if($data[$index]['id'] == $id){
            $data[$index]['time'] = date('Y-m-d H:i:s', time());
            $judge = true;
          }
        }
 
        if($judge){
          setcookie('RecordLuHuiDUDU',json_encode($data),time()+3600*24*30);
          return true;
        }
 
        if($num == 10){
          for($i = 0; $i < 9; $i++){ $data[$i] = $data[$i+1]; } $data[9] = array( 'id' => $id,
            'time' => date('Y-m-d H:i:s', time())
          );
        }
        if($num <10){ $data[$num] = array( 'id' => $id,
            'time' => date('Y-m-d H:i:s', time())
          );
        }else {
          return false;
        }
      }
    }
    setcookie('RecordLuHuiDUDU',json_encode($data),time()+3600*24*30);
    return true;
  }
