我想实现这么一个功能怎么实现?
我希望一个 static 变量,第一次访问时,为0 ,
以后每次访问都 +1,
我页面里这么写:
if(!isset($tmp))
static $tmp=0;
$tmp++;
echo 'fucking number:'.$tmp;
不起作用啊,每次$tmp都变回0了, 如何使得 $tmp 只设置一次为0 ?
------解决方案--------------------
你首先要明白每次访问的生命周期,如果你是某个人的 可以用session,如果是所有访问的用户共享就必须使用文件或者数据库了。
------解决方案--------------------
你先去看看php沉思录,估计你从别的语言转过来的?
PHP脚本在每次被解释时进行初始化,在解释完毕后终止运行。这种运行是互相独立的,每一次请求都会创建一个单独的进程或线程,来解释相应的页面文件。
所以你每次执行,tmp都为0,如果要保持结果,你就只有存入文件或数据库
------解决方案--------------------
全局变量吧.
session_start();
$_SESSION['tmp'];

看看这个可能对你有帮助
------解决方案--------------------
用session
或者
数据库吧

把值存入库或者写到文本里边。。。。

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.
