Overview

You can use a phpinfo() page to view the current PHP information for your server.

This file outputs a large amount of information, such as:

  • Information about PHP compilation options and extensions
  • PHP version
  • Server information and environment (if compiled as a module)
  • PHP environment
  • OS version information, paths, master and local values of configuration options
  • HTTP headers
  • PHP license

Because every system is set up differently, phpinfo() is commonly used to check PHP configuration settings and for available predefined variables on your particular system.

phpinfo() is also a valuable debugging tool, as it contains all EGPCS (Environment, GET, POST, Cookie, and Server) data.

Create a phpinfo.php page

  1. To create a phpinfo file, open a plain text file, add the following lines, and save:

    Filename: phpinfo.php

    
    <?php
    
    // Show all information, defaults to INFO_ALL
    phpinfo();
    
    ?>
    

    NOTE:

    Your phpinfo.php file needs to be a plain text file. This means you need to make it in a text editing program capable of producing plain text files.

    • On a Windows machine, you can use Notepad, which is one of your built-in accessories.
    • On a Mac, you can use TextEdit. You must first open the TextEdit "Preferences" menu and, in the "New Document" section, select "Plain text." Then, you should start a new document in TextEdit for your phpinfo.php file.
  2. Upload the file to the server. You should upload your file to the exact directory you want to test. Typically, this will be your html (/home/00000/domains/example.com/html/) httpdocs (/var/www/vhosts/example.com/httpdocs/) directory, although you can upload it to any subdirectory on your server as well. Use FTPFTP to upload the file.
  3. Visit the page in your browser. If you uploaded it to your html directory, you should now visit http://www.example.com/phpinfo.php, replacing example.com with your own domain name.
  4. Now you can view all of the information about PHP for your server for that particular directory.

TIP:

You can use CTRL-F (Windows) or COMMAND-F (Mac) in most browsers to open a quick search function. This is useful for browsing through long web pages quickly, and a phpinfo page is very long.

Grid pre-made phpinfo links

On the Grid, you can visit the following links to view the PHP information for your server. Replace 00000 with your site number.
