If you've dabbled in PHP, there comes times when you need to see what certain settings are on your server. You see what the server settings are by uploading a phpinfo.php file to the root directory.

Here's what the phpinfo.php file code looks like:

phpinfo.php

 PHP | 
 copy code |
?
 
1
<?php
2
phpinfo();
3
 
4
phpinfo(INFO_MODULES);
5
 
6
?>

source: http://php.net/manual/en/function.phpinfo.php

Use ftp to upload this file to your hosting account's root directory. You can see your server's settings my navigating to the absolute path to the file in a web browser.

Example: http://www.mywebsite.com/phpinfo.php
