CSDN bug 不能换行
这是第一行这是第二行
这是第四行(第三行空)
这是我提交BUG的链接http://bbs.csdn.net/topics/390532303
为甚么会出这种情况呢?
回复讨论(解决方案)
观看网页源代码,正文为
<div class="post_body"> 这是第一行这是第二行这是第四行(第三行空)这是我提交BUG的链接http://bbs.csdn.net/topics/390532303为甚么会出这种情况呢?没有了 HTML 换行标记,自然就不能换行了
对于类 post_body 有这样的处理代码
$('.post .post_body blockquote').each(function(index, item) { var first_child = $(item).find(':first'); if($(item).contents().get(0) !== undefined && $(item).contents().get(0).nodeName.toLowerCase() === 'br' && first_child.prop('tagName').toLowerCase() === 'br') { first_child.remove(); } });但显然不能作用于正文
PHP输出代码出了什么问题呢?
额 百度了下CSDN貌似不是PHP写的...
感觉CSDN好山寨啊 代码用了好多年了吧 UI重新设计一下呗 用户体验不好
无论是什么语言的,但凡是为用户着想的就不会出现此类问题

这句话真是精辟啊
之前貌似是正常的 不知道是具体什么代码引发了这个问题呢...

现在好了吧。
昨天就不能换行,应该人为失误操作。

还有,只能说明csdn测试人员力度不够啊。。。
现在能换行了,再看源码

版大你说的是直接原因... 咱们看到的这些网页不是动态生成的么我就想是什么语句导致了生成的这些html带或者没有带
,而又是什么样情况下会进行这种改动呢?/...
好吧纯粹是我的八卦之心
如果是 php 只不过是有没有 nl2br 函数的问题
其他语言没有这个函数,需要手写字符替换代码
估计是他想减轻服务器负担,而把替换放到浏览器中去执行。但是代码没写好
开来你不是一般的闲啊,居然找这些bug

其实这个界面已经够用了。

PHP is a server-side scripting language used for dynamic web development and server-side applications. 1.PHP is an interpreted language that does not require compilation and is suitable for rapid development. 2. PHP code is embedded in HTML, making it easy to develop web pages. 3. PHP processes server-side logic, generates HTML output, and supports user interaction and data processing. 4. PHP can interact with the database, process form submission, and execute server-side tasks.

PHP has shaped the network over the past few decades and will continue to play an important role in web development. 1) PHP originated in 1994 and has become the first choice for developers due to its ease of use and seamless integration with MySQL. 2) Its core functions include generating dynamic content and integrating with the database, allowing the website to be updated in real time and displayed in personalized manner. 3) The wide application and ecosystem of PHP have driven its long-term impact, but it also faces version updates and security challenges. 4) Performance improvements in recent years, such as the release of PHP7, enable it to compete with modern languages. 5) In the future, PHP needs to deal with new challenges such as containerization and microservices, but its flexibility and active community make it adaptable.

The core benefits of PHP include ease of learning, strong web development support, rich libraries and frameworks, high performance and scalability, cross-platform compatibility, and cost-effectiveness. 1) Easy to learn and use, suitable for beginners; 2) Good integration with web servers and supports multiple databases; 3) Have powerful frameworks such as Laravel; 4) High performance can be achieved through optimization; 5) Support multiple operating systems; 6) Open source to reduce development costs.

PHP is not dead. 1) The PHP community actively solves performance and security issues, and PHP7.x improves performance. 2) PHP is suitable for modern web development and is widely used in large websites. 3) PHP is easy to learn and the server performs well, but the type system is not as strict as static languages. 4) PHP is still important in the fields of content management and e-commerce, and the ecosystem continues to evolve. 5) Optimize performance through OPcache and APC, and use OOP and design patterns to improve code quality.

PHP and Python have their own advantages and disadvantages, and the choice depends on the project requirements. 1) PHP is suitable for web development, easy to learn, rich community resources, but the syntax is not modern enough, and performance and security need to be paid attention to. 2) Python is suitable for data science and machine learning, with concise syntax and easy to learn, but there are bottlenecks in execution speed and memory management.

PHP is used to build dynamic websites, and its core functions include: 1. Generate dynamic content and generate web pages in real time by connecting with the database; 2. Process user interaction and form submissions, verify inputs and respond to operations; 3. Manage sessions and user authentication to provide a personalized experience; 4. Optimize performance and follow best practices to improve website efficiency and security.

PHP uses MySQLi and PDO extensions to interact in database operations and server-side logic processing, and processes server-side logic through functions such as session management. 1) Use MySQLi or PDO to connect to the database and execute SQL queries. 2) Handle HTTP requests and user status through session management and other functions. 3) Use transactions to ensure the atomicity of database operations. 4) Prevent SQL injection, use exception handling and closing connections for debugging. 5) Optimize performance through indexing and cache, write highly readable code and perform error handling.

Using preprocessing statements and PDO in PHP can effectively prevent SQL injection attacks. 1) Use PDO to connect to the database and set the error mode. 2) Create preprocessing statements through the prepare method and pass data using placeholders and execute methods. 3) Process query results and ensure the security and performance of the code.

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),
