android json php
$response = array();include("conn.php");
$conn=mysql_open();
$sql =mysql_query('set names utf8');
mysql_query($sql);
if (isset($_POST['name'])) {……………………为甚么会提示未定义的name呢?name就是android发送过来的
回复讨论(解决方案)
你不是json么?你发送的内容是什么?你这么问别人怎么知道呢.出错的信息又是什么呢?就是个提示吧

params.add(new BasicNameValuePair("name", name));
JSONObject json = jsonParser.makeHttpRequest(url_up, "POST", params);以post方式发送
那php端$_POST['name']为什么得不到数据呢?我调试的时候是先运行android程序,然后再打开浏览器,显示没有接收到数据,数据库中也未成功插入数据

看是否获取到name,你可以讲值保存到文件中。因为安卓程序一打开就调用你的php文件了,你再打开文件,肯定妹纸了
先运行android程序,然后再打开浏览器
???
这样能行么?

事实证明是我的android程序写得有问题,url地址中IP写错了。但也奇怪了,我是笔记本见了一个临时局域网,然后手机连接到这个网络上了,所以我的IP就写的这个网络的IP,但是是事实证明要写电脑所连接的路由的网络的IP。
$data = file_get_contents("php://input");这样才能接收到数据,因为PHP默认只识别application/x-www.form-urlencoded标准的数据类型,因此,对型如text/xml 或者 soap 或者 application/octet-stream 之类的内容无法解析.

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.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
