Then click Open and the system will continue to install automatically. If the system prompts you multiple times to specify a folder, you can select this I386 folder and click OK, and the system will continue the installation.
After successful installation, the interface is as follows.
4. Configure PHP
1. Modify php.ini-production in the php folder and change it to php.ini.
2. Find ;extension_dir="./" in php.ini, remove the semicolon in front of it, and change it to extension_dir="d:/oServer/php/ext"
3. Find the following statement and remove the preceding semicolon
extension=php_gd2.dll
extension=php_mbstring.dll
extension=php_mysql.dll
extension=php_pdo.dll
extension=php_pdo_mysql.dll
extension=php_mcrypt.dll
Find ; date.timezone = remove the preceding semicolon,
Change to date.timezone =Asia/Shanghai
5. Configure IIS to support PHP
Open IIS and start configuring PHP
Find Website>Default Website, right-click the mouse and click Properties.
Click "ISAPI Filter", then click the "Add" button. In the pop-up "Filter Properties" dialog box, fill in the filter name "PHP" and the executable file "d:oServerphpphp5isapi.dll"
Click "Configuration" under the "Home Directory" tab, the "Application Configuration" dialog box will appear, click the "Add" button, in the pop-up "Add/Edit Application Extension Mapping" dialog box, in the executable file location Enter "d:oServerphpphp5isapi.dll", enter ".php" for the extension, and then OK.
Select Document, click Add and then enter index.php in the Default Content page and click OK.
Set "web server extension" in IIS Manager
Right-click on the blank area on the right and "Add a new Web service extension"
In the pop-up window: fill in ".php" for the extension, then click the Add button, browse to the php5isapi.dll file under the PHP installation package, and click OK. Then check Set extended status bits allowed. After the setup is complete,
Restart IIS.
Restart IIS
Create a new txt text file in the website directory
Enter the following:
phpinfo();
?>
Save as test.php (note that the extension cannot be test.php.txt)
Enter http://localhost/test.php in the browser. If the following interface appears, the installation is successful!

PHP remains important in modern web development, especially in content management and e-commerce platforms. 1) PHP has a rich ecosystem and strong framework support, such as Laravel and Symfony. 2) Performance optimization can be achieved through OPcache and Nginx. 3) PHP8.0 introduces JIT compiler to improve performance. 4) Cloud-native applications are deployed through Docker and Kubernetes to improve flexibility and scalability.

PHP is suitable for web development, especially in rapid development and processing dynamic content, but is not good at data science and enterprise-level applications. Compared with Python, PHP has more advantages in web development, but is not as good as Python in the field of data science; compared with Java, PHP performs worse in enterprise-level applications, but is more flexible in web development; compared with JavaScript, PHP is more concise in back-end development, but is not as good as JavaScript in front-end development.

PHP and Python each have their own advantages and are suitable for different scenarios. 1.PHP is suitable for web development and provides built-in web servers and rich function libraries. 2. Python is suitable for data science and machine learning, with concise syntax and a powerful standard library. When choosing, it should be decided based on project requirements.

PHP is a scripting language widely used on the server side, especially suitable for web development. 1.PHP can embed HTML, process HTTP requests and responses, and supports a variety of databases. 2.PHP is used to generate dynamic web content, process form data, access databases, etc., with strong community support and open source resources. 3. PHP is an interpreted language, and the execution process includes lexical analysis, grammatical analysis, compilation and execution. 4.PHP can be combined with MySQL for advanced applications such as user registration systems. 5. When debugging PHP, you can use functions such as error_reporting() and var_dump(). 6. Optimize PHP code to use caching mechanisms, optimize database queries and use built-in functions. 7

The reasons why PHP is the preferred technology stack for many websites include its ease of use, strong community support, and widespread use. 1) Easy to learn and use, suitable for beginners. 2) Have a huge developer community and rich resources. 3) Widely used in WordPress, Drupal and other platforms. 4) Integrate tightly with web servers to simplify development deployment.

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.
