The phpinfo() function outputs a huge amount of information about the system you're using, such as (for example):

  • PHP Version
  • PHO environment
  • PHP options and extension available
  • OS version
  • predefined variables
  • ... and many others...

To create a phpinfo file, simply open a plain text file in your web space, name it phpinfo.php, and insert in it the following line:

<?php
  phpinfo();
?>
