For example, take the root directory for the tree you want to display, loop through all the directories. Outside of this loop, create your <ul> tags. Inside the loop, check each directory to see if it has contents before you display it, and if it does, call the current function with the current directory as the argument. Then, the last item in your loop should be to display the current directory inside an <li> tag. I've used a derivative of this method for a recent project, but I had two functions, one to store the tree into a multi-dimensional array so I could sort the directories alphabetically, and then the second to display the sorted list.
