PHP中的date函数和time函数。
time()函数是获取当前的时间戳 从1970年1月1日 零点 零分 零秒
date()函数是格式化时间戳的。有没有人知道他是怎么格式化的呢?比如我有个时间戳 我能不能自己计算出时间呢?time()时间戳获取的是秒钟的累积和。但是我试着用时间戳除以60等于分。再除以60等于小时 在除以24怎么就不对了呢?
------解决方案--------------------
楼主是说获取时间戳除以一天24小时得到天数加上1970年
获取现在的时间。
问题是一年365天还是366天啊?
就像直接得到月份也是,28天一个月,31也是一个月!
------解决方案--------------------
那个秒数只能算到天。因为闰年的存在,所以不能简单得出。
------解决方案--------------------
function todate($time) //将时间化为日期
{
$arr=getdate($time);
echo $arr[year],"年",$arr[mon],"月",$arr[mday],"日",$arr[hours],"时",$arr[minutes],"分",$arr[seconds],"秒";
}
完美解决

- PHP code
function todate($time) //将时间化为日期{$arr=getdate($time);echo $arr[year],"年",$arr[mon],"月",$arr[mday],"日",$arr[hours],"时",$arr[minutes],"分",$arr[seconds],"秒";}<div class="clear"> </div>

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.
