Quick Drupal function reference

I got this little snippet off of drupal.org somewhere, but it's proving remarkabley handy for everyday development.

Create a php node with the following content: <?php print '

'; $functions = get_defined_functions(); foreach($functions['user'] as $function) { print "
1. $function
"; } print '

Then create a menu item that points to the node you just created.

You have a quick reference list of all available Drupal related function calls.
