本文主要介绍PHP5.2.11 + Apache2.2.19 + MySQL5.1.45的PHP集成运行环境的搭建(Windows XP SP3操作系统环境)
> 安装并配置APACHE(安装到C:\apache)
1、安装时默认安装,Network Domain, Server Name 我填写我的计算机名,Administrator's Email Address区域填你的邮件地址
2、安装完后在安装目录下有个conf文件夹,打开httpd.conf文件进行配置
·找到 DocumentRoot ,将其设置为你所要存放php, htm等网页文件的文件夹,如 "D:\phpapache\Apache2.2\htdocs";
·找到 DirectoryIndex ,在index.html后添加index.php, index.htm等,以单个空格将其分开;
·重启Apache,用http://localhost或http://127.0.0.1或http://yourcompanyname测试是否成功。成功的话屏幕会有个It works!
> 安装配置PHP(解压PHP压缩包到C:\php)
1、将php.ini-recommended文件重命名为php.ini并将其剪到系统所在目录下(如放在2000/NT的WINNT, XP的Windows目录下),
2、将extension_dir 改为php/ext所在目录,如 "C:\php\ext";
3、将doc_root 改为第一步中的同样目录,如 "C:\apache\htdocs";
4、找到 ;session.save_path = "/tmp" ,将';'去掉,设置你保存session的目录,如session.save_path = "C:/php/tmp";
5、然后把下面几句前面的分号去掉,以更好支持Mysql and PHPmyadmin
extension=php_mbstring.dll
extension=php_gd2.dll
extension=php_mysql.dll
extension=php_pdo.dll
extension=php_pdo_mysql.dll
> PHP+APACHE整合
1、允许Apache将PHP程序作为模块来运行:
打开httpd.conf,添加下面内容(位置任意):
LoadModule php5_module "C:/php/php5apache2_2.dll"
AddType application/x-httpd-php .php
AddType application/x-httpd-php .htm
(.htm, .php为可执行php语言的扩展名,也可加html, php3, php4,甚至txt)
(以下两步可以不需要)
2、如果你出于某种原因而需要在CGI模式中运行PHP程序(使用Php.exe),
请将上面这一行变成注释(各行头加#即可),添加下面这些行:
# ScriptAlias /php/ "C:/php/"
# AddType application/x-httpd-php .php
#Action application/x-httpd-php "/php/php-cgi.exe"
3、现在apache 2 支持HTML而不支持PHP,先把下面几句加到C:\apache\conf\httpd.conf去:
# ScriptAlias /php/ "C:/php/"
# AddType application/x-httpd-php .php
#Action application/x-httpd-php "/php/php-cgi.exe"
> 重启服务,测试环境
1、在C:\php里找到php5ts.dll,libmysql.dll将其复制到C:\winnt\system32下(winNT/2000的机器),而winXP/2003是复制到C:\windows\system32下
2、测试Apache与php是否连接成功:
启动start apache服务或者正在运行的就重新启动restart apache
3、在Web根目录下新建test.php(即C:\apache\htdocs目下)
phpinfo();
?>
4、运行http://localhost/test.php
如果成功,则应该看到一个含有PHP徽标的网页,其中包含大量设置和其他信息
那么恭喜你,环境已经搭建成功!

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.

In PHP, use the clone keyword to create a copy of the object and customize the cloning behavior through the \_\_clone magic method. 1. Use the clone keyword to make a shallow copy, cloning the object's properties but not the object's properties. 2. The \_\_clone method can deeply copy nested objects to avoid shallow copying problems. 3. Pay attention to avoid circular references and performance problems in cloning, and optimize cloning operations to improve efficiency.

PHP is suitable for web development and content management systems, and Python is suitable for data science, machine learning and automation scripts. 1.PHP performs well in building fast and scalable websites and applications and is commonly used in CMS such as WordPress. 2. Python has performed outstandingly in the fields of data science and machine learning, with rich libraries such as NumPy and TensorFlow.
