Yii是一个Web应用程序框架,用于快速开发现代Web应用程序。 Yii采用了最新的技术和设计模式,包括面向对象编程(OOP),MVC(模型,视图,控制器)架构,事件驱动编程等。 Yii具有卓越的性能和可扩展性,并支持多种数据库管理系统。
Yii的代码基于专有的BSD许可证。从法律上讲,BSD许可证允许您使用Yii的代码,并且不需要您将您自己的代码改写为公共领域或遵循相似的许可证。但是,您必须遵守几个规则:
下面是BSD许可证的原文:
Redistribution and use in source and binary forms, with or without modification,
are permitted provided that the following conditions are met:
1. Redistributions of source code must retain the above copyright notice,
this list of conditions and the following disclaimer.
2. Redistributions in binary form must reproduce the above copyright notice,
this list of conditions and the following disclaimer in the documentation and/or
other materials provided with the distribution.
THIS SOFTWARE IS PROVIDED BY THE COPYRIGHT HOLDERS AND CONTRIBUTORS "AS IS" AND
ANY EXPRESS OR IMPLIED WARRANTIES, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES
OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE ARE DISCLAIMED. IN NO EVENT
SHALL THE COPYRIGHT OWNER OR CONTRIBUTORS BE LIABLE FOR ANY DIRECT, INDIRECT, INCIDENTAL,
SPECIAL, EXEMPLARY, OR CONSEQUENTIAL DAMAGES (INCLUDING, BUT NOT LIMITED TO, PROCUREMENT
OF SUBSTITUTE GOODS OR SERVICES; LOSS OF USE, DATA, OR PROFITS; OR BUSINESS INTERRUPTION)
HOWEVER CAUSED AND ON ANY THEORY OF LIABILITY, WHETHER IN CONTRACT, STRICT LIABILITY,
OR TORT (INCLUDING NEGLIGENCE OR OTHERWISE) ARISING IN ANY WAY OUT OF THE USE OF THIS SOFTWARE,
EVEN IF ADVISED OF THE POSSIBILITY OF SUCH DAMAGE.
Yii还提供了私有授权选项,可以允许您对Yii的代码进行更多自由的修改和重新分发,而无需遵守BSD许可证的所有规则。 Yii的私有授权通常适用于需要Yii代码的商业应用程序和服务。
请注意,Yii的私有授权不是免费的。您需要支付许可证费用,费用不同,取决于您使用Yii的方式和用途。请咨询Yii的开发团队获取更多信息。
以下是一个简单的PHP代码片段,演示如何使用Yii的授权:
<?php
// Yii 授权声明
$copyright = "
This file is part of the Yii framework (http://www.yiiframework.com/).
Copyright (c) 2008-".date('Y')." Yii Software LLC.
All rights reserved.
";
// 输出声明
echo $copyright;
?>
该代码片段输出了Yii授权的版权声明,以及年份和版权所有方的名称。您可以将此代码片段包含在您的Yii应用程序中,以满足BSD许可证的第一个要求。为了符合Yii的使用规则,请不要删除或修改这段代码。
