phpinfo
On occasion it is useful to see what your php settings are. You can create a php page using the phpinfo() function from within your own Drupal install, if you can create php type content. This is probably not a page you would want to leave permanently, but it can be useful for finding specific information.
Create a page of php content type and copy and paste the following line into it:
<?php
phpinfo();
?>It will probably mess up your site's formatting.
Consider Devel Module
If you find yourself doing this sort of thing often, consider using the devel module during the development phase (http:drupal.org/project/devel).
The devel block includes a phpinfo() menu item. Plus there is a heap of other useful things that you'll use from time to time.
