Install PHP4 into IIS5 in Win2000_PHP Tutorial
The purpose of this article is to tell you how to configure PHP4 into your IIS5 under Win2000 Professional. I use Windows2000 Professional Chinese version, IIS5 Chinese version and PHP4.0RC1-Win32. This preview version of PHP4 is a pre-release version after 4 beta tests and can be downloaded from PHP's official site www.php.net. Be careful not to download the wrong one. The PHP4.0 Release Candidate 1 Source is prepared for Unix users. What you need is the PHP 4.0 Release Candidate1 Binaries for Win32.
Note that you need to install IIS5 first, because Win2000 Professional forgets it during the default installation. There is no need to discuss the installation method of IIS5 here. If you have any questions, please refer to other information.
OK!
The first step is to unzip the PHP4.0RC1-Win32.ZIP compressed package. You can put it under C:PHP4.
The second step is to copy the php.ini-dist file under C:PHP4 to the WINNT directory and rename it to php.ini. You don't need to modify any parameters to run it. Of course, you can modify some parameters according to different situations.
The third step is to copy C:PHP4Projectsphp4Release_TS_inlinephp4ts.dll to the C:WINNTsystem32 directory.
The fourth step is to click Start/Run and enter cmd to start the command line.
Step 5: Type the command mmc winntsystem32compmgmt.msc on the command line to start computer management.
Step 6: Expand "Services and Applications"/"Internet Information Services" on the computer management window, right-click on "Default Web Site" and select Properties. The system will pop up "Default Web Site Properties" Window:
Step 7: Click the "ISAPI Filter" tab on the "Default Web Site Properties" window, click the "Add" button, and enter the "Filter Name" in the pop-up "Filter Properties" window. "PHP", enter "C:PHP4Projectsphp4sapiisapiRelease_TS_inlinephp4isapi.dll" in "Executable File", OK.
Step 8: Click the "Home Directory" tab in the "Default Web Site Properties" window, click the "Configure" button, click the "Add" button in the pop-up "Application Configuration" window, and click the "Add" button in the pop-up "Application Configuration" window. In the "Add/Edit Application Extension Image" dialog box, enter "C:PHP4Projectsphp4sapiisapiRelease_TS_inlinephp4isapi.dll" in the "Executable File" text box, and enter ".php" in the "Extension" text box (note that there must be that dot ),Sure.
Step 9: Return to the command line window and enter the "net stop iisadmin" command to terminate the IIS service. The system will ask you if you want to stop related services, answer yes.
Step 10, enter the "net start w3svc" command to restart the IIS service.
OK, your configuration is now over. Let’s write a PHP program to test whether the configuration is successful! Edit a file named hello.php with the content:
echo "Hello, World!";

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.

PHP is not dead. 1) The PHP community actively solves performance and security issues, and PHP7.x improves performance. 2) PHP is suitable for modern web development and is widely used in large websites. 3) PHP is easy to learn and the server performs well, but the type system is not as strict as static languages. 4) PHP is still important in the fields of content management and e-commerce, and the ecosystem continues to evolve. 5) Optimize performance through OPcache and APC, and use OOP and design patterns to improve code quality.

PHP and Python have their own advantages and disadvantages, and the choice depends on the project requirements. 1) PHP is suitable for web development, easy to learn, rich community resources, but the syntax is not modern enough, and performance and security need to be paid attention to. 2) Python is suitable for data science and machine learning, with concise syntax and easy to learn, but there are bottlenecks in execution speed and memory management.

PHP is used to build dynamic websites, and its core functions include: 1. Generate dynamic content and generate web pages in real time by connecting with the database; 2. Process user interaction and form submissions, verify inputs and respond to operations; 3. Manage sessions and user authentication to provide a personalized experience; 4. Optimize performance and follow best practices to improve website efficiency and security.

PHP uses MySQLi and PDO extensions to interact in database operations and server-side logic processing, and processes server-side logic through functions such as session management. 1) Use MySQLi or PDO to connect to the database and execute SQL queries. 2) Handle HTTP requests and user status through session management and other functions. 3) Use transactions to ensure the atomicity of database operations. 4) Prevent SQL injection, use exception handling and closing connections for debugging. 5) Optimize performance through indexing and cache, write highly readable code and perform error handling.

Using preprocessing statements and PDO in PHP can effectively prevent SQL injection attacks. 1) Use PDO to connect to the database and set the error mode. 2) Create preprocessing statements through the prepare method and pass data using placeholders and execute methods. 3) Process query results and ensure the security and performance of the code.

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),
