如题所示.百度了下,说是名字一样,但ID不同,通过数组来解决。但是我还是不得要领。先把切换的代码发上。

我在page-10这个页面上是这样写的:
$cx=$_POST['cx'];
echo "$cx[1]";
?>
得到的结果就是个框框,说是乱码也不对,因为改成$cx[2]或者是$cx[0]都是同样的结果。
你在 page-10.php 中
print_r($_POST);
看看都有些什么

找到错误了,在修改那一项中出现问题。谢谢,也让我学到去用print_r检查。
谢谢咯,版主总能看到你的身影。麻烦你了。
我是半路出家,学校这学期没有开这门课,而这学期又有一个关于数据库的课程设计,我就要用到这个。马马虎虎把php的语法看了(可能学了C和C++,感觉还是很难容易上手),就开始着手课程设计了,反正是用到什么学什么,一点也不扎实,决定在暑假专门找些书系统学习下。
但是很迷茫学习的路线。我先说说我的看法。
html--->css---->php---->js
版主,看下,这样可以不?

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.
