回复内容:

我觉得题主说的“毁掉”的意思可能是是毁掉PHP超低的入门门槛。

感觉越写越像Java。

然而不可避免的,要接受改变。

在ES6刚出的时候也有很多人说ES6毁了JavaScript.原型继承的写法多么多么好。class写法多么多么糟。

时间证明,ES6标准正在快速被实现。

我相信,PHP正在越变越好(这句话又要被黑了)

关于严格模式:

从目前来看我觉得新项目用PHP的话,还是开了严格模式比较好。

因为7.1会加上JIT,性能会提升更多。不给返回值类型JIT不好做啊。

对于新手来说,不开严格模式学习也不会有太大的问题。

总之,我觉得PHP7是个好事。

我就等3号发布正式版升级了~

话说什么时候能把那些语法整理一下啊,都二十年了,咱函数名调整一下吧。要不然就被黑一辈子了 T_T 题主可以看下PHP7的修改记录,PHP7新特性 - PHP7
php7的改进还是非常合理的,越来越规范,消除了很多歧义的地方。错误处理也越来越统一。我非常看好PHP7的发展。 鸟哥 哭晕在厕所 php5会像ie6一样。


php这样的技术,是用来服务于生产的。贴近实际,省钱,才是硬道理。如果我追求性能,一开始或许就不会选择php。 鸟哥说,PHP7的目的是给广大的PHP程序员提供『透明』的性能提升。也就是更少的兼容性问题,更大的性能提升。

所以,你的『顾虑』根本是没有必要的。如果技术决策者认为这个升级有必要,那么必然会推动这个事,反之也并不会有什么影响。

PS:就在今天下午,领导说我们要准备升级PHP 7和HTTP 2.0的相关事宜了,让我这个喜欢新事物的家伙激动的虎躯一震啊! 每一次新版本的发布都会伴随着掌声和口水,但趋势是向着更好,更先进,更加符合时代需要发展的,抱着欣赏的态度你才能发现美。 不邀自来。。
据我所知,php目前对于性能的提升的很大的,对于自身的处理速度优化了很多,同时也改变了一些语法的使用。
但是话说回来,php现在对于速度的提升你说好吗,当然好,速度快了总归是好的,但是现在真正的大公司真的只是用单纯的一门语言来撑起自己的技术?难道处理大数据也要php做?做桌面应用也要php做?我说肯定不是得,就像是数据库一样,难道nosql火起来了就没人用mysql了吗。肯定不是得,各有各的优势。互相配合,用好语言本身的优势才是正道

歪一句。
你这个题很容易变成黑php专栏,请题主做好没什么干货的准备。。 鸟哥吐血中 php5的地位至少五到六年内在国内都无法动摇,尤其是像php7这种大跨度的升级。原本的系统是否兼容?技术人员的水平是否跟得上?是否需要培训?运维管理的流程是否需要改变?这些都是实打实的成本,如果把各种成本都折算成资金成本,你确定比你买几台硬件设备更便宜?
这就是为什么国内还有一大堆用php5.2,甚至php4的企业。
当然,这对网上的“技术宅”们来说肯定是各种LOW,各种顽固守旧了,说什么php7性能怎样怎样,业界阻碍科技发展什么什么的,毕竟自己的个人博客站想怎么玩怎么玩,说出来顺便提高逼格。
所以,我认为php7肯定会给php续命,说不定Python和Ruby都过气了,那些考不上大学的年轻人都还在学php当饭碗,沾一下IT行业的光,但普及的过程会比较缓慢,尤其在国内。 有什么毁不毁的,你认为php7难,那么你先学php5吧。同理,ES6,ES5也一样!

What are some common problems that can cause PHP sessions to fail?What are some common problems that can cause PHP sessions to fail?Apr 25, 2025 am 12:16 AM

Reasons for PHPSession failure include configuration errors, cookie issues, and session expiration. 1. Configuration error: Check and set the correct session.save_path. 2.Cookie problem: Make sure the cookie is set correctly. 3.Session expires: Adjust session.gc_maxlifetime value to extend session time.

How do you debug session-related issues in PHP?How do you debug session-related issues in PHP?Apr 25, 2025 am 12:12 AM

Methods to debug session problems in PHP include: 1. Check whether the session is started correctly; 2. Verify the delivery of the session ID; 3. Check the storage and reading of session data; 4. Check the server configuration. By outputting session ID and data, viewing session file content, etc., you can effectively diagnose and solve session-related problems.

What happens if session_start() is called multiple times?What happens if session_start() is called multiple times?Apr 25, 2025 am 12:06 AM

Multiple calls to session_start() will result in warning messages and possible data overwrites. 1) PHP will issue a warning, prompting that the session has been started. 2) It may cause unexpected overwriting of session data. 3) Use session_status() to check the session status to avoid repeated calls.

How do you configure the session lifetime in PHP?How do you configure the session lifetime in PHP?Apr 25, 2025 am 12:05 AM

Configuring the session lifecycle in PHP can be achieved by setting session.gc_maxlifetime and session.cookie_lifetime. 1) session.gc_maxlifetime controls the survival time of server-side session data, 2) session.cookie_lifetime controls the life cycle of client cookies. When set to 0, the cookie expires when the browser is closed.

What are the advantages of using a database to store sessions?What are the advantages of using a database to store sessions?Apr 24, 2025 am 12:16 AM

The main advantages of using database storage sessions include persistence, scalability, and security. 1. Persistence: Even if the server restarts, the session data can remain unchanged. 2. Scalability: Applicable to distributed systems, ensuring that session data is synchronized between multiple servers. 3. Security: The database provides encrypted storage to protect sensitive information.

How do you implement custom session handling in PHP?How do you implement custom session handling in PHP?Apr 24, 2025 am 12:16 AM

Implementing custom session processing in PHP can be done by implementing the SessionHandlerInterface interface. The specific steps include: 1) Creating a class that implements SessionHandlerInterface, such as CustomSessionHandler; 2) Rewriting methods in the interface (such as open, close, read, write, destroy, gc) to define the life cycle and storage method of session data; 3) Register a custom session processor in a PHP script and start the session. This allows data to be stored in media such as MySQL and Redis to improve performance, security and scalability.

What is a session ID?What is a session ID?Apr 24, 2025 am 12:13 AM

SessionID is a mechanism used in web applications to track user session status. 1. It is a randomly generated string used to maintain user's identity information during multiple interactions between the user and the server. 2. The server generates and sends it to the client through cookies or URL parameters to help identify and associate these requests in multiple requests of the user. 3. Generation usually uses random algorithms to ensure uniqueness and unpredictability. 4. In actual development, in-memory databases such as Redis can be used to store session data to improve performance and security.

How do you handle sessions in a stateless environment (e.g., API)?How do you handle sessions in a stateless environment (e.g., API)?Apr 24, 2025 am 12:12 AM

Managing sessions in stateless environments such as APIs can be achieved by using JWT or cookies. 1. JWT is suitable for statelessness and scalability, but it is large in size when it comes to big data. 2.Cookies are more traditional and easy to implement, but they need to be configured with caution to ensure security.
