This article describes how to use the phpinfo() function to view detailed information about the PHP environment, settings, and more.

View PHP settings with phpinfo Function

You often need to check PHP settings during web development. You can do this by running a script that calls the phpinfo() function. When you load the page in a web browser, the script shows all of the PHP configuration settings for your web site.

To use the phpinfo() function to view PHP settings:

1. Create a file that contains the following code:

   <?php
       phpinfo();
   ?>

2. Save the file as info.php or something similar.
3. Upload the file to your public_html directory.

4. Use your browser to go to http://example.com/info.php, where example.com represents your web site's domain name. The page displays a large amount of information about the PHP installation.
   

   For security reasons, you should disable any calls to the phpinfo() function when web site development and testing is complete.
