分享一个php cookie操作类，用到了php中的命名空间，这个比较新颖，有需要的朋友参考下吧。

一个php cookie操作类，实现了基本的操作功能：

创建cookie、设置cookie的过期时间、注销cookie等。

代码：

name = (string) $name)){

if(!is_null($value)){

$this->value = (string) $value;

$this->expire = $expire;

$this->path = $path;

$this->domain = $domain;

$this->secure = $secure;

$this->httponly = $httponly;

} else {

$this->value = $this->exists() ? $_COOKIE[$this->name] : '';

}

} else {

throw new Exception("invalid cookie name");

}

}

/**

* 检测cookie是否存在

* @return boolean

*/

public function exists(){

return isset($_COOKIE[$this->name]);

}

/**

* 通过setcookie设置cookie信息

*/

public function save(){

return setcookie($this->name, $this->value, $this->expire, $this->path, $this->domain, $this->secure, $this->httponly);

}

/**

* 注销cookie

*/

public function delete(){

return setcookie($this->name, "", time() - 3600);

}

}

}

?>
