页面传值
我想做一个在一个页面传值。
例如 text.php
链接
$tt=$_GET['id'];
echo $tt;
?>
就是页面进入后先判断如果有值传入,执行代码1,如果没有值传入,执行代码2
这个判断弄不好了 不知道怎么判断
还有看过别人的页面 一个页面有很多传值 都是自身,例如www.xxx.com/edit....
是怎么个思路
我自己写 经常一个功能要写好几个配php页面 有什么的办法没?
------解决方案--------------------
if(isset($tt))
代码1
else
代码2

楼主你好www.xxx.com/edit....这种形式使用的是框架技术,就我个人熟悉点的是ZF(ZendFramework)。一个MVC模式的框架技术,可以实现你的想法的,而且不需要使用大量的PHP文件来实现一个功能。
这里有个很好,很出名的ZF的入门Demo,地址是http://akrabat.com/zend-framework-tutorial/
你可以下载他的源码和PDF教程进行框架的学习,之后你会发现,不知不觉就达到你想要的效果啦!祝成功!

- PHP code
if (!empty($_GET['id'])) { //执行a $id = intval($_GET['id']); include('./a.php'); } else { //执行b include('./b.php'); } <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.
