Use of PHP's own framework session() (perfect part 6)

1. PHP’s own framework session()

 

 

 2、session类（SessionBase.php）

<?php
class SessionBase
{
    /**
     * 设置session
     */
    public static function set($name, $data, $expire=600){
        $session_data = array();
        $session_data['data'] = $data;
        $session_data['expire'] = time()+$expire;
        $_SESSION[$name] = $session_data;
    }
    /**
     * 读取session
     */
    public static function get($name){
        if(isset($_SESSION[$name])){
            if($_SESSION[$name]['expire']>time()){
                return $_SESSION[$name]['data'];
            }else{
                self::clear($name);
            }
        }
        return false;
    }

    /**
     * 清除session
     * @param String $name session name
     */
    private static function clear($name){
        unset($_SESSION[$name]);
    }

}

3. Encapsulate session class function.php

function session(){
    $num=func_num_args();
    $session=new SessionBase();
    if($num>=2){
        if($num==3){
            //三个参数
            $expire=func_get_arg(2);
        }else{
            //二个参数
            $expire=3600;
        }
        $session::set(func_get_arg(0),func_get_arg(1),$expire);
        return true;
    }else{
        //一个参数
        return   $session::get(func_get_arg(0));
    }
}

4. Call session (indexCrl.php)

<?php
class indexCrl extends  CrlBase {
    public function index(){
        //设置session
        session('name','haha',60);
        //获取session
        var_dump(session('name'));
        //清空session
        session('name',null);
    }

}
