php + nginx 安装
今天尝试了下在WIN2K3系统下用nginx做服务器来跑PHP。
为什么要用nginx?
小巧免安装。
为什么要fastcgi?
nginx下如果php不用fastcgi模式 就要用代理模式那样还要配置个Apache 之类麻烦。。
直接到http://windows.php.net/download去下载个PHP 的ZIP包
有四个不同类型的版本,VC9 x86 Non Thread Safe、VC9 x86 Thread Safe、VC6 x86 Non Thread Safe、VC6 x86 Thread Safe 怎么选择呢?
一、如何选择PHP5.3的VC9版本和VC6版本
??? VC6版本是使用Visual Studio 6编译器编译的,如果你的PHP是用Apache来架设的,那你就选择VC6版本。
??? VC9版本是使用Visual Studio 2008编译器编译的,如果你的PHP是用IIS来架设的,那你就选择VC9版本。
二、如何选择PHP5.3的Thread Safe和Non Thread Safe版本
??? 先从字面意思上理解,Thread Safe是线程安全,执行时会进行线程(Thread)安全检查,以防止有新要求就启动
新线程的CGI执行方式而耗尽系统资源。Non Thread Safe是非线程安全,在执行时不进行线程(Thread)安全检查。
??? 再来看PHP的两种执行方式:ISAPI和FastCGI。
??? ISAPI执行方式是以DLL动态库的形式使用,可以在被用户请求后执行,在处理完一个用户请求后不会马上消失,所以需要进行线程安全检查,这样来提高程序的执行效率,所以如果是以ISAPI来执行PHP,建议选择Thread Safe版本;
??? 而FastCGI执行方式是以单一线程来执行操作,所以不需要进行线程的安全检查,除去线程安全检查的防护反而可以提高执行效率,所以,如果是以FastCGI来执行PHP,建议选择Non Thread Safe版本。
因为我电脑上有VC9库并且我要用nginx跑PHP-fastcgi 所以直接下VC9 x86 Non Thread Safe版本的ZIP免安装版本
注:如果没装请到微软下载Microsoft Visual C++ 2008 SP1 Redistributable Package (x86)安装即可!
安装PHP:
1、解压php-5.3.0-nts-Win32-VC9-x86.zip 到D:\php;
2、复制D:\php\php.ini-development并重命名为D:\php\php.ini
3、记事本编辑D:\php\php.ini
1)设定系统默认时区为中国
????? 查找;date.timezone =
??? 改为date.timezone =PRC
2)设置扩展包目录
????? 查找; extension_dir = "ext"
????? 改为extension_dir = "ext"
3)开启gd2、mysql等扩展包
????? 分别查找;extension=php_gd2.dll和extension=php_mysql.dll
?????? 去掉前面的;即可
4)在的D:\php下新建个记事本文件
????? 内容php-cgi.exe -b 127.0.0.1:9000 -c php.ini
????? 重命名或另存为startup.bat???
安装nginx
1、到http://sysoev.ru/nginx/download.html下载nginx最新的windows版本nginx/Windows-0.8.21.zip
2、解压nginx-0.8.21.zip到D:\
3、用记事本打开D:\nginx-0.8.21\conf\nginx.conf
4、查找#location ~ \.php$ {
??? 将
??????? #location ~ \.php$ {
??????? #??? root?????????? html;
??????? #??? fastcgi_pass?? 127.0.0.1:9000;
??????? #??? fastcgi_index index.php;
??????? #??? fastcgi_param SCRIPT_FILENAME /scripts$fastcgi_script_name;
??????? #??? include??????? fastcgi_params;
??????? #}
??? 改为
??????? location ~ \.php$ {
??????????? root?????????? html;
??????????? fastcgi_pass?? 127.0.0.1:9000;
??????????? fastcgi_index index.php;
??????????? fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
??????????? include??????? fastcgi_params;
??????? }
?? 5、查找 location / {
??? 将 location / {
??????????? root?? html;
??????????? index index.html index.htm;
??????? }
?? 改为location / {
??????????? root?? html;
??????????? index index.html index.htm index.php;
??????? }
?
参考:http://blog.meiu.cn/nginx-proxy_cache.html
?? 保存并关闭nginx.conf
===============我是传说种的分界线=============
启动服务:
进入d:\php\执行startup.bat启动php_fastcgi
进入D:\nginx-0.8.21打开nginx.exe
打开进程管理器可以看到进程里有两个nginx.exe一个php-cgi.exe的进程说明启动成功
浏览http://localhost/
打开文件夹D:\nginx-0.8.21\html
删除里面的index.html并新建index.php内容为
刷新http://localhost/
这样为纯净绿色安装如果要让服务每次开机都会自动运行请自行添加为系统服务。

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),
