Often when we run our software on a server, many system errors halt the process. This can happen if your configuration does not meet the specific system requirements. Finding even the basic information about your PHP configuration can be tricky. But we can create a single PHP info file showing us all details about our PHP configuration.
In this blog, we will discuss how to create and use the phpinfo file using your hosting control panel. So without any further wait, let’s start learning!
phpinfo() Function
PHP provides us with a built-in function called phpinfo() which displays the details about the current PHP version and its configuration installed on our system. It is a very useful debugging tool as it contains every EGPCS (Environment, GET, POST, Cookie, Server) data.
Syntax:
phpinfo(int $flags = INFO_ALL): true
You can also try this code with Online PHP Compiler

Steps to Create phpinfo Page
Follow the below steps to create a phpinfo page for your site.
Step 1: Create a phpinfo file on your device. Open your preferred text editor and write down the below code.
Now save this file with the name info.php on your device.
Step 2: Open up any FTP client and connect your site’s server with your credentials.
Step 3: In the file section, click on the Online File Manager.
Step 4: Now go to the htdocs folder or create any custom folder and click on the upload button.
Step 5: Upload the info.php file we created using the text editor.
Congratulations! You have successfully added the php info page to your site.
Accessing phpinfo Page on Your Browser
Now that you have uploaded your phpinfo file on your server, it will be available publicly. Anyone can view your phpinfo page by adding /info.php to the end of your site’s domain name.
Now if you didn’t specify any parameter, it would return the complete PHP information page, which is quite long. In order to locate the specific file details, you can use the Find function on your browsers by clicking CTRL + F on your computer.
Edit or Rename phpinfo page
You can edit the uploaded php.info file as well as rename it even after uploading it. Just right-click on the php.info file, and you can see various options available for your file.
Delete phpinfo file
As your info.php file is available publicly, it is prone to many attacks. Attackers may use various tools/bots to exploit your sensitive data. Therefore, it is best to delete the info.php file once you are done using it.
In order to delete the file, click info.php file > delete > confirm.
This will delete the uploaded info.php file from your FTP client.
