Summary of online game exercises (1), _PHP tutorial
网游练习总结(1),
最近一段时间在校也闲得没事干,反正是好长一段时间,干脆就做一个《中国象棋》网游耍耍打发时间。弄了好久没有写总结,以及整个过程中遇到的问题,今天就赶紧写一哈,难免后面就会忘了。
一、注册登录界面:
可能会说这么简单的游戏,网上可能例子很多,也没有必要弄注册这样的功能,其实我只是学着玩玩哈。
关于注册我使用的是php与as3.0交互做的,有与php学的非常浅,也遇到了不少问题:
1.检测是否注册成功:这个也困了时间不是很长,但是觉得比较重要,我搜了一些资料找到的:
mysql_affected_rows()// 函数返回前一次 MySQL 操作所影响的记录行数。执行成功,则返回受影响的行的数目,如果最近一次查询失败的话,函数返回 -1。
2.邮箱激活验证:

这个需要配置SMTP服务,现在QQ邮箱网易邮箱等都可以去设置,然后作为代理邮箱。
$smtp = new smtp($smtpserver,$smtpserverport,true,$smtpuser,$smtppass);<br />$smtp->debug = false;//关闭调试<br />$state = $smtp->sendmail($smtpemailto, $smtpusermail, $mailtitle, $mailcontent, $mailtype);<br />
在整个数据库操作过程中使用一个变量来监控是否出现操作错误,来返回是否注册成功;
error_reporting(E_ERROR | E_WARNING | E_PARSE);//屏蔽所有错误警告等

Resource id #num
由于本人是一枚初学者,对mysql查询返回值等理解不够,遇到了一点困惑,mysql_query() 仅对 SELECT,SHOW,EXPLAIN 或 DESCRIBE 语句返回一个资源标识符,如果查询执行不正确则返回 FALSE。要使用mysql_fatch_array()函数或者mysql_fetch_object()函数进行转换,然后对相应数组或者对象进行操作。
总的来说这部分遇到的困难也不是很多,经过自己的努力很快就解决了。

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),
