关于php时区时间错误问题??
http://czy4411741.blog.163.com/blog/static/342031272008123115233915/
从php5.1.0开始,php.ini里加入了date.timezone这个选项,默认情况下是关闭的
也就是显示的时间(无论用什么php命令)都是格林威治标准时间
和我们的时间(北京时间)差了正好8个小时,有以下3中方法可以恢复正常的时间。
1,最简单的方法就是不要用php5.1以上的版本
2,如果一定要用,而且不能修改php.ini,则需要在关于时间的初始化的语句的
上面加上 date_default_timezone_set (XXX);
cp无此问题
3,一劳永逸,仅限能修改php.ini。打开php.ini查找date.timezone 去掉前面的分号
= 后面加XXX,重启http服务(如apache2或iis等)即可
关于XXX,大陆内地可用的值是:Asia/Chongqing ,Asia/Shanghai ,Asia/Urumqi (依次为重庆,上海,乌鲁木齐)
港台地区可用:Asia/Macao ,Asia/Hong_Kong ,Asia/Taipei (依次为澳门,香港,台北)
还有新加坡:Asia/Singapore
老外好像把北京漏调了
其他可用的值是:Etc/GMT-8 ,Singapore ,Hongkong ,PRC
PRC是什么?PRC是中华人民共和国啊-_-
---------------------------------------------
解决方式:
在页头使用date_default_timezone_set()设置我的默认时区为北京时间
date_default_timezone_set('PRC');
echo date('Y-m-d H:i:s');
时间和服务器当前时间一样了!!祝贺之
?
附date_default_timezone_set用法如下
?
--------------------------------
date_default_timezone_set
(PHP 5 >= 5.1.0RC1)date_default_timezone_set -- 设定用于一个脚本中所有日期时间函数的默认时区
说明
bool date_default_timezone_set ( string timezone_identifier )
date_default_timezone_set() 设定用于所有日期时间函数的默认时区。
?
?
注: 自 PHP 5.1.0 起(此版本日期时间函数被重写了),如果时区不合法则每个对日期时间函数的调用都会产生一条 E_NOTICE 级别的错误信息。
?
参数
?
?
?
时区标识符,例如 UTC 或 Europe/Lisbon
?
返回值
本函数永远返回 TRUE(即使 timezone_identifier 参数不合法)。

再附上时区标识符:

What’s still popular is the ease of use, flexibility and a strong ecosystem. 1) Ease of use and simple syntax make it the first choice for beginners. 2) Closely integrated with web development, excellent interaction with HTTP requests and database. 3) The huge ecosystem provides a wealth of tools and libraries. 4) Active community and open source nature adapts them to new needs and technology trends.

PHP and Python are both high-level programming languages that are widely used in web development, data processing and automation tasks. 1.PHP is often used to build dynamic websites and content management systems, while Python is often used to build web frameworks and data science. 2.PHP uses echo to output content, Python uses print. 3. Both support object-oriented programming, but the syntax and keywords are different. 4. PHP supports weak type conversion, while Python is more stringent. 5. PHP performance optimization includes using OPcache and asynchronous programming, while Python uses cProfile and asynchronous programming.

PHP is mainly procedural programming, but also supports object-oriented programming (OOP); Python supports a variety of paradigms, including OOP, functional and procedural programming. PHP is suitable for web development, and Python is suitable for a variety of applications such as data analysis and machine learning.

PHP originated in 1994 and was developed by RasmusLerdorf. It was originally used to track website visitors and gradually evolved into a server-side scripting language and was widely used in web development. Python was developed by Guidovan Rossum in the late 1980s and was first released in 1991. It emphasizes code readability and simplicity, and is suitable for scientific computing, data analysis and other fields.

PHP is suitable for web development and rapid prototyping, and Python is suitable for data science and machine learning. 1.PHP is used for dynamic web development, with simple syntax and suitable for rapid development. 2. Python has concise syntax, is suitable for multiple fields, and has a strong library ecosystem.

PHP remains important in the modernization process because it supports a large number of websites and applications and adapts to development needs through frameworks. 1.PHP7 improves performance and introduces new features. 2. Modern frameworks such as Laravel, Symfony and CodeIgniter simplify development and improve code quality. 3. Performance optimization and best practices further improve application efficiency.

PHP type prompts to improve code quality and readability. 1) Scalar type tips: Since PHP7.0, basic data types are allowed to be specified in function parameters, such as int, float, etc. 2) Return type prompt: Ensure the consistency of the function return value type. 3) Union type prompt: Since PHP8.0, multiple types are allowed to be specified in function parameters or return values. 4) Nullable type prompt: Allows to include null values and handle functions that may return null values.
