How to create and use the phpinfo.php file

Often while troubleshooting a problem or installing Wordpress, users seek information regarding which version of PHP they are using as well as other server related information. Apart from PHP, users may need information regarding MySQL and the OS being used. For users who do not have information about the phpinfo file, this information may be difficult to find. However, they can easily find this information without having to search their site for long or without asking their host.

The phpinfo() function can be easily used to collect all the server related information. This function queries the server and generates a long report with a vast set of data. The file may have some moderately sensitive information which can be utilized by hackers to gain access to your server. So, the best way out is to give this file an obscure name and not the regular phpinfo.php name. You can give it an obscure name like fghd546.php. Apart from that, once you have checked out the required information, you can delete this file.

You can create this file in the root folder of your site using either SSH or SFTP connection. For example, you can SSH to your server and then change directory to the root folder:

cd /var/www/html

After that, you can open the file using nano:

Sudo nano fghd546.php

Now, paste the following content into this file:

<?php phpinfo(); ?>

Make sure there are no spaces before or after the function. Close and save the file. Otherwise, you can create the file using notepad and then upload it to your root folder using a SFTP client like Cyberduck or Filezilla. Once you have collected the required information, you can also delete this file.

Now, you just need to go to that page on your website such as and you will be able to find detailed information regarding php version, OS and other things. The report is multiple pages long.
