基本上用了一天的时间,才把环境配好,还不是手动配置的,而是用的windows installer。弄了好几遍,但是手动配置的总是不能运行,没有办法啊!Windows的好处可见一般,它把只有专业人员能使用的东西,推广到了千家万户。微软的理念,让桌面电脑进入每一个家庭,真的不是天才的设想。不过,一开始想啊:我一个学习计算机的却贪图省事,好意思吗!呵呵,真的是有点不好意思!然而,只要能在最快的时间内作好工作,那么简单一点又有什么不好的呢?关键是达到目的!!!可以不择手段的,当然我这样说没有其他的意思,呵呵! 不多说了,贴出我的第一个PHP程序:
Hello World! title >
head >
// Single line C++ style comment
/*
printing the message
*/
echo "Hello World!
";
# Unix style single line comment
print strftime("%m/%d/%Y");
echo PHPINFO();
?>
BODY >
HTML >
里面PHPINFO()的函数,我看一本书上,是这样写的:PHP_INFO(),书有点旧了,后来改成现在的样子才好,不知道是怎么回事,也没有深究。
第一印象,PHP这东西挺好玩的,嘿嘿,也是个很不错的WEB开发的选择,挺强大的、开源,给人耳目一新的感觉!
安装过程在这也提一下吧:
1 下载安装php-5.0.4-installer.exe,我用的WEB服务器是IIS6,没有考虑安全。主要是方便,自己学习用!
2 mysql-4.1.8-win.zip,setup.exe安装即可,还没有去进一步的去看它的用法,好像还有好多的东西要配置。
3 下载和配置PHPMYADMIN,MYSQL的管理工具,可见PHP和MYSQL的不一般的关系!
我现在把自己对PHP的学习看作是业余爱好!

PHP remains a powerful and widely used tool in modern programming, especially in the field of web development. 1) PHP is easy to use and seamlessly integrated with databases, and is the first choice for many developers. 2) It supports dynamic content generation and object-oriented programming, suitable for quickly creating and maintaining websites. 3) PHP's performance can be improved by caching and optimizing database queries, and its extensive community and rich ecosystem make it still important in today's technology stack.

In PHP, weak references are implemented through the WeakReference class and will not prevent the garbage collector from reclaiming objects. Weak references are suitable for scenarios such as caching systems and event listeners. It should be noted that it cannot guarantee the survival of objects and that garbage collection may be delayed.

The \_\_invoke method allows objects to be called like functions. 1. Define the \_\_invoke method so that the object can be called. 2. When using the $obj(...) syntax, PHP will execute the \_\_invoke method. 3. Suitable for scenarios such as logging and calculator, improving code flexibility and readability.

Fibers was introduced in PHP8.1, improving concurrent processing capabilities. 1) Fibers is a lightweight concurrency model similar to coroutines. 2) They allow developers to manually control the execution flow of tasks and are suitable for handling I/O-intensive tasks. 3) Using Fibers can write more efficient and responsive code.

The PHP community provides rich resources and support to help developers grow. 1) Resources include official documentation, tutorials, blogs and open source projects such as Laravel and Symfony. 2) Support can be obtained through StackOverflow, Reddit and Slack channels. 3) Development trends can be learned by following RFC. 4) Integration into the community can be achieved through active participation, contribution to code and learning sharing.

PHP and Python each have their own advantages, and the choice should be based on project requirements. 1.PHP is suitable for web development, with simple syntax and high execution efficiency. 2. Python is suitable for data science and machine learning, with concise syntax and rich libraries.

PHP is not dying, but constantly adapting and evolving. 1) PHP has undergone multiple version iterations since 1994 to adapt to new technology trends. 2) It is currently widely used in e-commerce, content management systems and other fields. 3) PHP8 introduces JIT compiler and other functions to improve performance and modernization. 4) Use OPcache and follow PSR-12 standards to optimize performance and code quality.

The future of PHP will be achieved by adapting to new technology trends and introducing innovative features: 1) Adapting to cloud computing, containerization and microservice architectures, supporting Docker and Kubernetes; 2) introducing JIT compilers and enumeration types to improve performance and data processing efficiency; 3) Continuously optimize performance and promote best practices.

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),
