IIS
本文是在Windows 2000简体中文正式版(IIS5.0)的环境下写出来的,在Windows NT 4.0的IIS4.0上应该也适合,有任何问题烦请告诉本人,在此谢谢各位,^_^
1、软件下载:
http://www.php.net/distributions/php-4.0.0-Win32.zip
2、用WinZIP等解压缩工具把php-4.0.0-Win32.zip解开到PHP安装目录,如C:\PHP,本文中
用$PHP_ROOT来代替PHP安装目录;
3、详细的英文安装文档请参考$PHP_ROOT目录下的README.txt文件;
4、将$PHP_ROOT目录下的php.ini-dist文件拷贝到C:\WINNT目录,并将C:\WINNT\php.ini-d
ist改名为C:\WINNT\php.ini;
5、将$PHP_ROOT目录下的MSVCRT.DLL和php4ts.dll拷贝到C:\WINNT\system32目录,如果
C:\WINNT\system32目录下已经存在这些文件,请不要覆盖;
6、修改C:\WINNT\php.ini:
1) 将extension_dir设置为PHP安装目录,如:extension_dir = C:\PHP
2) 配置要加载的动态裢接库(DLL),注意一定要保证只能加载$PHP_ROOT目录下存在
的动态裢接库,该版本自带这些动态裢接库:php_calendar.dll、php_imap.dll、php_ldap
.dll,因此动态裢接库的配置栏如下:
;Windows Extensions
extension=php_calendar.dll
extension=php_imap.dll
extension=php_ldap.dll
7、点击"开始->程序->管理工具->Internet 服务管理器"打开"Internet 服务管理器",右
击"默认Web站点->属性"打开"默认Web站点属性"窗口,在"ISAPI筛选器"配置页下,添加一
个新的筛选器,筛选器名称为PHP,可执行文件为php4isapi.dll文件的完整路径$PHP_ROOT\
php4isapi.dll,如C:\PHP\php4isapi.dll;在"主目录"配置页下,按"配置"按钮打开"应用
程序配置"窗口,添加一个应用程序映射项,可执行文件为php4isapi.dll文件的完整路径
$PHP_ROOT\php4isapi.dll,如C:\PHP\php4isapi.dll,扩展名为.php(当然也可以改成别的
,不过要注意您的PHP程序要以它为后缀哦),把"脚本引擎"打上勾;
8、建一个PHP程序测试目录,如D:\MyPHP,在本文中用$MyPHP来代替该目录,在"Internet
服务管理器"中,右击"默认Web站点->新建->虚拟目录",别名为MyPHP,实际路径为$MyPHP
中的路径,在本例中为D:\MyPHP,有读取、运行脚本和浏览权限;
9、重新启动WWW服务;
10、在$MyPHP目录下写一个测试程序phpinfo.php(注意后缀要和7中的扩展名一致哦),内容
为 phpinfo(); ?>,然后在浏览器上输入http://localhost/myphp/phpinfo.php测试,能
看到PHP信息就表示安装好了。

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.

Key players in HTTP cache headers include Cache-Control, ETag, and Last-Modified. 1.Cache-Control is used to control caching policies. Example: Cache-Control:max-age=3600,public. 2. ETag verifies resource changes through unique identifiers, example: ETag: "686897696a7c876b7e". 3.Last-Modified indicates the resource's last modification time, example: Last-Modified:Wed,21Oct201507:28:00GMT.

In PHP, password_hash and password_verify functions should be used to implement secure password hashing, and MD5 or SHA1 should not be used. 1) password_hash generates a hash containing salt values to enhance security. 2) Password_verify verify password and ensure security by comparing hash values. 3) MD5 and SHA1 are vulnerable and lack salt values, and are not suitable for modern password security.

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.
