Creating a PHP Info Page is a straightforward process that can be completed in just a few steps.

You can access the PHP Info Page by typing phpinfo() in your browser's address bar, assuming PHP is installed and configured correctly.

The PHP Info Page provides a wealth of information about your server and PHP setup, including the PHP version, server information, and loaded extensions.

To create a custom PHP Info Page, you can use the phpinfo() function in a PHP script, which will display the same information as the default PHP Info Page.

PHP Info Page Functionality

The phpinfo() function is a powerful tool for displaying PHP configuration information. It's especially useful for debugging attempts, as it generates EGPCS data.

You can run phpinfo() without any parameters to display all available information. However, there are also a handful of parameters you can use to access only the specific information you want to see. These include INFO_GENERAL, INFO_CREDITS, INFO_CONFIGURATION, INFO_MODULES, INFO_ENVIRONMENT, INFO_VARIABLES, and INFO_LICENSE.

One way to use the phpinfo() function is by creating a phpinfo page. This is a simple method to access the function's output without having to run it directly in your code. You can also use the WordPress Site Health feature in version 5.2 and above to confirm your web server details, memory limit, and PHP version.

The phpinfo() function displays a wide range of information, including the current version of PHP, server information and environment, operating system version information, and HTTP headers. It also shows modules and extensions currently in use, as well as master and local values for PHP configuration options.

Here are some of the key parameters you can use with the phpinfo() function:

  • INFO_GENERAL: Displays the configuration line, web server, OS, and more.
  • INFO_CREDITS: Shows a list of PHP developers, modules, etc.
  • INFO_CONFIGURATION: Returns the current local and master directives.
  • INFO_MODULES: Shares all extensions and their settings.
  • INFO_ENVIRONMENT: Includes all environment variable information.
  • INFO_VARIABLES: Shows all predefined variables from Environment, GET, POST, Cookie, Server (EGPCS).
  • INFO_LICENSE: Displays the PHP License.

By using the phpinfo() function, you can easily access a wide range of PHP configuration information, making it a valuable tool for debugging and troubleshooting.

Working with PHP Files

To access the PHP information on your server, you can create a phpinfo file in your public_html directory. This file will be accessible via a browser and will show you the same detailed information as the built-in PHP Info feature.

If your hosting platform doesn't offer the built-in PHP Info feature, creating a phpinfo file is a simple solution. You can create the file by navigating to your File Manager, clicking the New File button, and naming it phpinfo.php.

To edit the phpinfo file, you can use any text editor on your computer, such as Notepad, or edit it directly in the File Manager. Simply copy and paste the following code into the text editor and press Save: Navigate to File Manager under the Files section in your hPanel.Once you’re in public_html directory, click the New File button.Name your file phpinfo.php and press Create.Scroll down and locate the new phpinfo file within the directory, then right-click to Edit.Now, copy and paste the following code into the text editor and press Save.

Delete or Rename Your Page

You should delete your phpinfo page once you're done using it. This is because some of the information it returns is sensitive and could help a hacker gain access to your server.

Attackers may use bots to search for phpinfo pages to exploit them, so it's best to delete it. You can do so by returning to your FTP client.

Alternatively, you can rename your phpinfo page to help hide it from hackers. Use a random string of letters and numbers instead of "phpinfo".

Renaming the file changes the URL you use to access your phpinfo page, so make sure to remember the new name. You'll need to use it to access the page whenever you like.

However, renaming the file isn't a guaranteed solution for preventing a security breach. It's still possible for hackers to recognize the file and breach security.

You can rename your phpinfo page to something like "phpinfo_disabled" to easily disable the file.

If you don't want your phpinfo page to be displayed all the time, you can easily disable the file by giving it a different name, as suggested in Example 4. For example, you can rename the file to phpinfo.php_disabled.
