PHP操作SESSION针对屌丝框架

记得 session_start();

class Session{

/**
* 设置session
* @param String $name   session name
* @param Mixed  $data   session data
* @param Int    $expire 超时时间(秒)
*/
public static function set($name, $data, $expire=600){
$session_data = array();
$session_data['data'] = $data;
$session_data['expire'] = time()+$expire;
$_SESSION[$name] = $session_data;
}

/**
* 读取session
* @param  String $name  session name
* @return Mixed
*/
public static function get($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]);
}

}
