Configuring and running a PHP application on IIS requires the following steps: 1. Install IIS and PHP, make sure IIS is enabled and download the PHP ZIP file. 2. Add a website or application in IIS Manager and configure the handler to map to the PHP executable. 3. Use simple PHP scripts to test the configuration. 4. Debug by checking log files and error logs. 5. Optimize performance, including using application pools and adjusting php.ini settings.
introduction
In today's web development world, PHP is still the preferred language for many developers, and IIS (Internet Information Services) is also widely used in enterprise environments as Microsoft's web server. Using PHP with IIS can provide developers with a powerful platform to build and deploy web applications. This article aims to provide you with a comprehensive guide to configuring and running PHP applications on IIS from scratch. By reading this article, you will learn how to install and configure PHP, how to solve common problems, and how to optimize the performance of your PHP application on IIS.
Review of basic knowledge
PHP is a widely used open source universal scripting language, especially suitable for web development and can be embedded in HTML. IIS is a web server software developed by Microsoft and is often used in Windows server environments. Understanding the basics of PHP and IIS is our first step toward configuration. PHP installation packages usually include FastCGI modules, which is essential for running PHP on IIS, because IIS itself does not directly support PHP.
Before configuring, make sure that IIS is installed on your Windows server. You can add or remove Windows features through Programs and Features in the Control Panel of Windows to make sure IIS is enabled.
Core concept or function analysis
The configuration and function of PHP on IIS
Configuring PHP on IIS mainly involves installing PHP and configuring IIS to support the execution of PHP scripts. The installation of PHP can be downloaded by downloading the officially published ZIP file and then decompressing it to a directory on the server. To configure IIS, you need to add a new website or application in the IIS Manager and map the handler to the PHP executable file.
// Simple PHP script for testing PHP configuration on IIS <?php echo "Hello, World! This is PHP running on IIS."; ?>
This simple script can help you verify that PHP is configured and run correctly on IIS.
How it works
When a PHP request reaches IIS, IIS will pass the request to the FastCGI handler, which then calls the PHP executable file to process the PHP script. After the PHP script is executed, the generated HTML content will be returned to IIS through FastCGI, and IIS will eventually send these contents to the client browser.
This mechanism allows PHP to run efficiently on IIS, but there are some details that need to be paid attention to, such as the settings in PHP's configuration file (php.ini) may affect performance and security.
Example of usage
Basic usage
The most basic usage of running PHP on IIS is to create a new website or application and place the PHP file at the root of the website. Here is a simple example showing how to create a new PHP website on IIS:
// index.php <?php echo "Welcome to my PHP site on IIS!"; ?>
In IIS Manager, add a new website, point to the directory containing index.php, and make sure the PHP handler is configured correctly.
Advanced Usage
For more complex applications, you may need to configure URL rewrite rules, set virtual directories, or use IIS's application pool to isolate different PHP applications. Here is an example of rewriting using a URL:
// .htaccess RewriteEngine On RewriteRule ^old-page\.php$ new-page.php [R=301,L]
On IIS, you need to use the URL rewrite module to achieve similar functionality, which can be configured via the "URL rewrite" function in the IIS manager.
Common Errors and Debugging Tips
Common errors when running PHP on IIS include PHP scripts that cannot be executed, permission issues, and FastCGI configuration errors. Here are some debugging tips:
- Check the IIS log file for detailed information about request processing.
- Use PHP's error log (php_error_log) to catch errors in PHP scripts.
- Ensure that the paths of PHP's executable and configuration files are correct.
Performance optimization and best practices
Performance optimization is a key consideration when running PHP on IIS. Here are some optimization suggestions:
- Use IIS's application pool to isolate different PHP applications, improving stability and security.
- Adjust PHP's configuration file (php.ini), such as increasing memory limits, adjusting maximum execution time, etc.
- Use IIS's caching capabilities, such as output cache and data cache, to reduce server load.
In practical applications, it is very important to compare the performance differences between different configurations. For example, enabling output caching can significantly improve page loading speed, but cache failure and updates are also required to consider.
Programming habits and best practices are equally important. Keeping your code readable and maintainable, such as using meaningful variable names, adding comments, and following code style guides, can greatly improve the efficiency of teamwork and maintainability of your code.
In short, using PHP with IIS is a powerful combination that can provide you with an efficient and stable web development and deployment platform. Through this article's guidance, you should be able to configure and optimize your PHP application on IIS with confidence.

How to get the current session ID in PHP?
Jul 13, 2025 am 03:02 AM
The method to get the current session ID in PHP is to use the session_id() function, but you must call session_start() to successfully obtain it. 1. Call session_start() to start the session; 2. Use session_id() to read the session ID and output a string similar to abc123def456ghi789; 3. If the return is empty, check whether session_start() is missing, whether the user accesses for the first time, or whether the session is destroyed; 4. The session ID can be used for logging, security verification and cross-request communication, but security needs to be paid attention to. Make sure that the session is correctly enabled and the ID can be obtained successfully.

To extract substrings from PHP strings, you can use the substr() function, which is syntax substr(string$string,int$start,?int$length=null), and if the length is not specified, it will be intercepted to the end; when processing multi-byte characters such as Chinese, you should use the mb_substr() function to avoid garbled code; if you need to intercept the string according to a specific separator, you can use exploit() or combine strpos() and substr() to implement it, such as extracting file name extensions or domain names.

How to split a string into an array in PHP
Jul 13, 2025 am 02:59 AM
In PHP, the most common method is to split the string into an array using the exploit() function. This function divides the string into multiple parts through the specified delimiter and returns an array. The syntax is exploit(separator, string, limit), where separator is the separator, string is the original string, and limit is an optional parameter to control the maximum number of segments. For example $str="apple,banana,orange";$arr=explode(",",$str); The result is ["apple","bana
JavaScript Data Types: Primitive vs Reference
Jul 13, 2025 am 02:43 AM
JavaScript data types are divided into primitive types and reference types. Primitive types include string, number, boolean, null, undefined, and symbol. The values are immutable and copies are copied when assigning values, so they do not affect each other; reference types such as objects, arrays and functions store memory addresses, and variables pointing to the same object will affect each other. Typeof and instanceof can be used to determine types, but pay attention to the historical issues of typeofnull. Understanding these two types of differences can help write more stable and reliable code.
Using std::chrono in C
Jul 15, 2025 am 01:30 AM
std::chrono is used in C to process time, including obtaining the current time, measuring execution time, operation time point and duration, and formatting analysis time. 1. Use std::chrono::system_clock::now() to obtain the current time, which can be converted into a readable string, but the system clock may not be monotonous; 2. Use std::chrono::steady_clock to measure the execution time to ensure monotony, and convert it into milliseconds, seconds and other units through duration_cast; 3. Time point (time_point) and duration (duration) can be interoperable, but attention should be paid to unit compatibility and clock epoch (epoch)
