How to solve the problem that php phpinfo cannot display php information

PHP is a very popular web development language that supports dynamic content development running on a web server. After you install PHP, you may encounter a problem, that is, PHP information cannot be displayed correctly when using the phpinfo() function. This problem can be due to many factors, and this article will cover ways to fix it.

1. Check whether the PHP installation directory is correct

When you use the phpinfo() function, it will find the PHP installation directory. If the PHP installation directory is not set correctly, you will not be able to display PHP information correctly. In this case, you need to confirm that the PHP installation directory is correct. You can view it by running the phpinfo() function. If the output information is not what you expect, it is recommended to search for the PHP.ini file on the server and check whether the PHP installation directory is correct.

2. Check whether the phpinfo() function is disabled

Some server security policies will disable the phpinfo() function. Disabling this function can prevent hackers from obtaining sensitive information of the server through this function. Therefore, in some cases, the phpinfo() function may be disabled due to security policy issues. You can try using other PHP functions to test whether the server is working properly.

3. Check if the PHP version is correct

PHP is a rapidly evolving language, and new versions will contain many updates and improvements. If the PHP version you are using is too low, the phpinfo() function may not be able to display PHP information correctly. Therefore, it is recommended to use the latest version of PHP to ensure that the phpinfo() function works properly.

4. Check Apache or Nginx configuration

In some cases, the configuration of Apache or Nginx may affect the working of the phpinfo() function. Checking whether Apache or Nginx is configured correctly is a very important step to solve this problem. Confirm that the PHP configuration is correct and check for any errors or issues in the Apache or Nginx configuration.

5. Check that PHP extensions and libraries are correct

PHP and many extensions require support from other libraries and modules to work properly. If PHP does not have the correct extensions and libraries, the phpinfo() function will not be able to obtain and display PHP information correctly. Therefore, you need to make sure that PHP extensions and libraries are installed correctly.

Summary:

In web development, PHP is very important. When using the phpinfo() function, you will find that PHP information cannot be displayed normally. This problem may be caused by factors such as the PHP installation directory, PHP version, Apache or Nginx configuration, PHP extensions and libraries, etc. By finding and solving the above problems, you can make the phpinfo() function work properly and play a better role in web development.
