429028 Need VERY simple PHP function 2

I have a table in MySQL with the following data (In the Parent column, a 0 indicates that this is a root category and has no parent): ID | TITLE | PARENT 1 | RACING | 0 2 | MARINE | 0 3 | DRAG RACING | 1 4 | DIRT RACING | 1 5 | TIMED RACE | 3 6 | BOATS | 2 I need a simple PHP function that will generate an HTML dropdown list like so: <option value="2">MARINE</option> <option value="6">MARINE-->BOATS</option> <option value="1">RACING</option> <option value="4">RACING-->DIRT RACING</option> <option value="3">RACING-->DRAG RACING</option> <option value="5">RACING-->DRAG RACING-->TIMED RACE</option> Basically a tiered select box, with everything sorted alphebatically. Each option should list the parent, if there is one. I need this function NOW, so if you can provide it NOW, you'll get the project NOW. Simple as that.
