[PHP] I fixed the logic :-) --- Recursive Array on outputing correctly

[Gregory Machin]

Here it is..
i found the problem.. 1) all the menu objects->arrChildren have an array ,
if there are on submenus.. then the array is empty .. the function was
trying to recurse through empty arrays. 2) the recursive call needed to
pass  the arrChildren to recurse correctly
"display_menu($value->arrChildren);"

now just to get the html output and css to live together :-)...

Thanks All form the support, all bets greg..
