How to install and configure IIS and PHP

IIS is a commonly used web server software in Windows operating systems, while PHP is a popular open source scripting language mostly used for web development. On Windows operating systems, by configuring IIS with PHP, you can implement an efficient web server and develop powerful web applications. In this article, you'll learn more about installing and configuring IIS and PHP.

1. Installation and configuration of IIS

1. Installing IIS

In the Windows operating system, IIS is a built-in Web server software that can be accessed through " Control Panel"->"Programs and Features"->"Turn Windows features on or off" to choose to install IIS. Among them, select "Internet Information Services".

2. Configuring IIS

After installing IIS, you need to configure some basic settings, including IP address, port, host name, security level, etc. It can be configured through "IIS Manager"->"Default Website"->"Properties". Among them, the specific configuration steps are as follows:

• IP address: Select the corresponding IP address or select all available IP addresses.
• Port: The default port is 80, which can be modified by yourself.
• Host name: The default is localhost, you can also modify it as needed.
• Security level: The security level can be set according to needs.

2. PHP installation and configuration

1. Installation of PHP

PHP can be installed using the XAMPP one-click installation package or manually Install. Here we take manual installation as an example. The installation steps are as follows:

• Download the PHP installation package, unzip it and place it in the directory you want to install. It is best to set the complete path.
• Create a new php.ini file in the directory and configure it into the environment variable so that it can be recognized.
• Open "CGI and ISAPI Restrictions" in IIS and add the PHP interpreter to it.

2. Configuring PHP

The configuration of PHP can better coordinate all PHP properties to adapt to your own needs. Common configuration methods are:

• Modify the php.ini file: you can adjust PHP's running time, file upload size, memory limit, etc.
• Modify the FastCGI settings in IIS: it can speed up the interpretation and operation of PHP.
• Using the phpinfo() function: You can view the details of the PHP configuration to better adjust its properties.

3. Integration of IIS and PHP

In order to make IIS and PHP work together smoothly, the following operations are required:

• In IIS Add Handler mapping in: Let IIS know the location of PHP's interpreter.
• Modify the file name of the PHP executable file: Because the default file name does not comply with IIS specifications, it needs to be changed to php-cgi.exe.
• Configure PHP test page: You can create a PHP test page to test whether PHP and IIS can collaborate.

4. Solutions to common problems

1. IIS cannot display the PHP page

At this time, you need to check whether the Handler mapping in IIS is correct. Check it in IIS Manager.

2. PHP code cannot be parsed

At this time, you need to check whether the PHP environment variable settings are correct and whether the PHP.ini file is loaded correctly.

3. PHP program cannot run

It may be because the file name of the PHP executable file has not been changed, that is, it has not been changed to php-cgi.exe.

In short, in a Windows environment, IIS and PHP can work perfectly together to provide developers with a fast and efficient web development environment. However, there are some details that need to be paid attention to. The installation and configuration steps described in this article can make the installation and configuration process simpler and easier.
